I was just reading some Tweets and an associated Hackernews thread and it reminded me that, now that I've left Mozilla for a while, it's safe for me to say: antivirus software vendors are terrible; don't buy antivirus software, and uininstall it if you already have it (except, on Windows, for Microsoft's).
Update (Perhaps it should go without saying --- but you also need to your OS to be up-to-date. If you're on Windows 7 or, God forbid, Windows XP, third party AV software might make you slightly less doomed.)
At best, there is negligible evidence that major non-MS AV products give a net improvement in security. More likely, they hurt security significantly; for example, see bugs in AV products listed in Google's Project Zero. These bugs indicate that not only do these products open many attack vectors, but in general their developers do not follow standard security practices. (Microsoft, on the other hand, is generally competent.)
Furthermore, as Justin Schuh pointed out in that Twitter thread, AV products poison the software ecosystem because their invasive and poorly-implemented code makes it difficult for browser vendors and other developers to improve their own security. For example, back when we first made sure ASLR was working for Firefox on Windows, many AV vendors broke it by injecting their own ASLR-disabled DLLs into our processes. Several times AV software blocked Firefox updates, making it impossible for users to receive important security fixes. Major amounts of developer time are soaked up dealing with AV-induced breakage, time that could be spent making actual improvements in security (recent-ish example).
What's really insidious is that it's hard for software vendors to speak out about these problems because they need cooperation from the AV vendors (except for Google, lately, maybe). Users have been fooled into associating AV vendors with security and you don't want AV vendors bad-mouthing your product. AV software is broadly installed and when it breaks your product, you need the cooperation of AV vendors to fix it. (You can't tell users to turn off AV software because if anything bad were to happen that the AV software might have prevented, you'll catch the blame.) When your product crashes on startup due to AV interference, users blame your product, not AV. Worse still, if they make your product incredibly slow and bloated, users just think that's how your product is.
If a rogue developer is tempted to speak out, the PR hammer comes down (and they were probably right to do so!). But now I'm free! Bwahahaha!

I really agree. It is particularly troubling for application software vendors, that it's essentially impossible to test against common AV software.ReplyDelete
The AV vendors update and patch their products frequently, modifying the way they hook the OS. They don't ever allow anyone access to pre-release versions. This is the kind of thing that, even with the best of intentions, causes problems.
As a long-time software developer, I have seen many problems caused by AV behaviour, particularly network hooks which modify traffic (TLS interception anyone?).

If not, then what?
I'd use whatever Apple offers; if they don't offer anything, then "nothing" is probably better than the usual A/V vendors. MacOS is locked down reasonably tightly already.Delete
If you are a business, Bromium. Not quite AV, but something better, imo, as it doesn't use signatures, but looks for aberrant behaviour; e.g your email should not be trying to access your customer database. Best of all, the way it works is to let the infection think it's succeeded, while recording what it's trying to do, and that can be shared without exposing your security.Delete
Mac's do not require any antivirus.Delete
Sir, i hope you never have childrenDelete
heheh... Yeah that is it.. Mac don't require antivirus.. They are immune to all digital threats.. You might want to search that on snopes.com!!!Delete
My wife is a graphic designer and uses nothing but Macs. Her company uses Macs. None have security on them. Is there Mac malware? Yes but far and few between.Delete
Mac's don't usually require antivirus software, because they have three significant deterrents. First is Malware Check, which functions similarly to Windows Defender, but runs silently in the background without any user interface. 99% of users never know that it's there.Delete
The second is GateKeeper. It's default configuration requires that any binaries be signed by a developer with an active developer account with Apple before it will run. (This can be disabled on an app-by-app basis or globally, but it is on by default). This allows malicious apps discovered in the wild to be disabled by Apple unless the user specifically re-enables them.
The third is that any app sold through the App Store undergoes a code review and also is required to be sandboxed from other processes.
So, while it's not perfect, given those three mechanisms, and the fact that the Mac installed base is less than 10% of windows, means that malware and viruses are virtually nonexistent on the Mac.
Just to be clear, if I'm not mistaken, Gatekeeper started with Lion (10.7), so those of us using Snow Leopard this advice is not relevent.Delete
"Mac's don't usually require antivirus software, because they have three significant deterrents."Delete
BS! Macs don't have as many issues with malware because they have such tiny market share, and malware creators don't target it as much. The simple fact is as an OS Windows is more secure and has fewer exploits. This isn't even debatable.
What about open source antivirus like ClamAV?ReplyDelete
I don't know much about it. Being open-source means it's probably less crazy-bad than the others. Still, I'd be skeptical that it's a significantly better recommendation than Windows Defender, for Windows 10 users.Delete
As far as I know, it is the only free (as in freedom) antivirus. If you need more security than that, just go free software full way and ditch MS Windows altogether in favor of a free OS such as GNU/Linux.Delete
1. ClamAV has poor virus detection rate 2. it is only a virus scanner (to be used on files or folders), it does not provide a resident shied checking the files before you open them.Delete
ClamAV is an AV solution you need to run manually. It is therefore a nice enough "stick behind the door" for tech savvy users, not your average Joe. There are ways to make ClamAV work as a real-time AV scanner, but that software isn't made by the people behind ClamAV, and the last time I tried it, my CPU had a continuous load of 30%.Delete
SO I use ClamAV sometimes, I use online AV scanners more often and monthly malware scans. No virus or malware on my system for 10 years. That said, I run a strictly configured router/firewall on a completely separate PC and every device that connects through my LAN is on a separate VLAN with even stricter rules. All of the computers I use have mostly PortableApps tools and browsers are as vanilla as possible, with the exception of 'uBlock Origin' and 'uMatrix'.

Hi Robert, what about applications such as https://heimdalsecurity.com/en/products/heimdeal-free that simply keep your average virus magnet applications up-to-date? Would you recommend that on the side, along with whatever the OS offers?ReplyDelete
You should stick to applications that are good at updating themselves. For example there's no need for Heimdal to update Firefox or Chrome, and getting it involved adds potential for catastrophic bugs.Delete
So it depends on what applications you use. If a random person asked me with no further information, I'd probably play it safe and say no since there's potential for badly-implemented updates to do great harm.

For home use I don't disagree with you. We all know that by the time the AV software finds an infection it's too late anyway. But a lot of businesses these days are allowing or requiring BYO devices with their user base. We have to protect everyone's systems. We can't have people running on networks in such an insecure way. Here, our security appliances & firewalls can help to mitigate security threats imposed by rogue devices, but that is not enough.ReplyDelete
Ideally, everyone just becomes more tech-aware and can figure out that they shouldn't click that link in their email because they probably aren't descended from African royalty.

I can't imagine why you'd allow regular users to attach BYO devices to your corporate network.Delete
That aside, what evidence is there that any third-party AV is a net security win over Microsoft's built-in stuff? I haven't seen any, even with all the comments around this post.
Calling the major vendors' products "anti virus" kind of highlights a lack of research, on your part. Apparmor/SELinux, for example, is pretty much considered best practice in the Linux world, so why is it that similar third party functionality in the suites that you dismiss as "AV" suddenly becomes worthless in the Windows world. There's much more to the major - let's call them what they are - HIPS software packages than you give them credit for.Delete
SELinux has all kinds of problems. However, at least it has defined interfaces; the source is open and operates in a transparent fashion; distros take responsibility for configuring it and making it work with their application packages; and it hasn't been a source of egregious security bugs.Delete
Windows AV on the other hand is a crazy mess of closed-source code doing random patching, hooking, parsing arbitrary complex data formats in ring 0 and other blunders, changing unpredictably, with practically no coordination.
windows is different to linux in this respect because software vendors are considered potentially hostile to the OS as they are frequently not aligned to its goals. linux distros on the other hand tend to provide software that is more closely matched to the OS because of its maintainers including or packaging them instead of vendors.Delete
This smells all too consumer to me. Users who are diligent about patching not only their OS but third party software as well (Reader, Java etc.) MAY be able to get away with nothing more than Defender; However, what ever happened to Defense in Depth? At any business or enterprise, you have to do your best to protect the data, employees as well as your customers. Sure, traditional AV isn't always going to protect you but most AV \ EPP vendors are doing their diligence to include technology in their products that go way beyond what traditional AV ever did. In addition, there are other products to consider like Application Whitelisting technology. Of course, these in concert with other technologies like DLP, IDS, NGFW, SIEM etc. can all help protect the business. Common Defense in Depth here. But to recommend either nothing or Microsoft built in offering is not the best approach if you care about the things you need to protect.ReplyDelete
"Defense in depth" does not mean that the answer to "should I install this 'security' product?" is always "yes".Delete
Each product you install adds vulnerabilities to your system as well as protecting you from some set of threats. The sets of threats overlap (e.g. if you're scanning email on the mail server, scanning it again on the client doesn't do much).
> But to recommend either nothing or Microsoft built in offering is not the best approach if you care about the things you need to protect.
I'd like to see an independent evidence-based evaluation of this. I haven't, and one hasn't turned up in all the comments around this post. Lacking one, and given the egregious blunders of the major AV vendors that have come to light, I still think being conservative in what you install, as I have advised, is perfectly reasonable for the average user.
I guess that one could then argue that since Microsoft also includes IE and/or Edge in their operating systems, one should not install Firefox, Opera, or Chrome either. After all, you are adding more software with more bugs and we do want to be conservative in what we install, right?Delete
If IE/Edge are installed but you don't use them, no problem.Delete

I believe you may be right about that which is why I suggested Microsoft's stuff.
The problem if you only use Windows defender (on Win 8.1 about myself) is that you could be infected by a virus (like a trojan) while browsing a web page with firefox.ReplyDelete
I've made EICAR tests with Windows defender and firefox and defender doesn't notice the viruses in a web page (but it works with IE 11).
EICAR-like tests are mostly meaningless for browsers. By the time malware has been around long enough to be analyzed and its signature(s) (binary, behavioural, whatever) blocked by AV tools, modern browsers will have already fixed whatever holes they were exploiting. Firefox doesn't need to explicitly detect Web-bourne viruses; Firefox's job is to make sure that all such content is harmless.Delete
For modern browsers that are kept up to date your real threats are zero-day exploits, which can easily evade any AV product.
I think I need a good AV also because a few weeks ago, i've been on a TV streaming webpage and there was a trojan into the page.Delete
It has been detected by my AV but not by Firefox.

I've done this since I understood a little more about how these security solutions work (5 or 6 years ago).ReplyDelete
I don't understand why Windows Defender is different from the others AV. If you could explain this point I would appreciate it.
I mentioned it in the post. Based on the data I've seen, I have a much higher opinion of Microsoft's people and processes than the other AV vendors. Also, because Microsoft's stuff ships with Windows they are more likely to get the integration right and be held to reasonable quality standards.Delete
Hooray another educated opinion from someone who does not actually fix PCs for a living.ReplyDelete
Thanks for that. You just made my job harder, but more profitable.
Microsoft themself say that their AV solution is "Baseline", which means is the lowest you should go, not the highest.
I keep seeing quotes about the crappy state of AV, but it always focuses on Norton, Mcafee etc., who are historically crap and simply sell more product.
Avira or Bitdefender never apear in these quotes or lists of bad AV/vendors.
I can find zero evidence that MS AV is any good, only the oposite, as the frequent infected PCs I have to fix are usually using either MSE/Defender, Norton or Mcafee, which is as good as using a magic 8-ball.
MS AV does not scan web page content in non-MS browsers, so malvertising and link scanning in FF or Chrome is non-existent.
If you are going to recommend MSE/Defender, at least show some evidence or reference to how good it is at its job, not mere opinion and belief.
It is provably consistently below average, and for a while fell off the bottom of the AV test/comparison sites.
Firefox and Chrome use Google Safe Browsing for URL filtering so it's not "non-existent".
Scanning Web content adds very little value. By the time malware has been around long enough to be analyzed and its signature(s) (binary, behavioural, whatever) blocked by AV tools, modern browsers will have already fixed whatever holes they were exploiting. Firefox doesn't need to explicitly detect Web-bourne viruses; Firefox's job is to make sure that all such content is harmless. AV products interfering with Firefox has historically made that more difficult --- including Avira and Bitdefender, as you can see above. Justin Schuh says it's the same for Chrome.
This all assumes users are using up-to-date OSes and browsers, as I updated my post to make clear.
Windows Defender may not be very good at the metrics you're talking about, but at least it does relatively little harm.
Well what if you never enable the plugings those AV products try to push onto your browser?Delete
That doesn't necessarily stop them hooking and patching browsers; i.e. that wouldn't stop all the bad stuff they do.Delete
"Windows Defender may not be very good at the metrics you're talking about, but at least it does relatively little harm."Delete
For the test suites that look at false negatives, Microsoft's consumer solutions are generally the king of the hill. How is that "relatively little harm"?

Which is why I never install browser addons that monitor/pre-empt/intercept/divert/parse or otherwise aggregate code or functionality into or onto my browsers, of which I use two: Chrome and FireFox. Nor do I lard on all the extra geegaws they beg you to buy. AND by-the-way, I never pay for AV software. I have used AVG Free, rightly or wrongly, in conjunction with FireFox (and now Chrome) for 18(?) years during which time I have fallen prey to an exploit only once and that was my fault. Any other security failures I experienced were with MSIE - and nothing could protect you from the flaws in MSIE. No AV product can protect you against your own stupidity, especially if you don't understand or acknowledge the shortcomings of the AV platform you use. I get the point about MSAV: who knows MS better than MS? Who better to create and build an AV architecture that works in harmony with MSOS, but then look at MSIE. I still think MSIE is terrible software and never use it. So I stick to what I know works, for now. But I will say this, and I wish someone would address this specific issue. What i fear, in light of the Russian exploit of the DNC, is that these foreign AV softwares could be engineered to backdoor any user and expose westerners to attack. Imagine planting evidence of criminal activity on thousands or millions of computers, implicating innocent users in criminal activities of which they have no knowledge and indictment for said crimes they did not commit: wire fraud, sex crimes, computer crimes, espionage, public infra-structure crimes, you name it, or leverage your system as a bot to attack dot-gov or public/private infrastructure. This has begun to steadily creep into my awareness of late.ReplyDelete

That don't even bench the Microsoft built in av because of its low scores.
I understand from a stand point of the browsers sake with their plugins. I don't even enable those because i want the browser to do that and the AV to catch anything the browser doesn't catch.
I've gone back and forth on this myself as an IT professional and I find myself using AV because of those listed sites and Microsoft's admission that it's just a baseline product they include.
To me performance is always what I'm looking for as I'm an avid PC gamer and I've never had issues with Bitdefender running on my PC slowing down my Games or Browsing.
I have though run into those issues you mentioned where it gets tricky because the AV product is doing some stuff with the kernel. For example Asus tools to monitor my PC and adjust setting like voltages and bus speeds has an issue with BitDefender. My response to that was just to not use the software and seek alternatives to monitor temps.
OK for the sake of time I'll just focus onDelete
> That don't even bench the Microsoft built in av because of its low scores.
This report does include Microsoft. In that test, MS got 97% (1570 out of 1619) ... lower than most of the other products, but the actual difference is very small.
The major problem with tests like this is that they are designed to fit the strengths of AV products and avoid their weaknesses. The report doesn't say how they acquire their malware samples, but I guess they get them from the same sources AV vendors do. (They're not writing their own since they say they independently verify that their malware samples "work" on an unprotected machine.) So what they're testing here is the ability of AV software to recognize malware that's been in the wild long enough to be recognized and added to someone's database. That's exactly the malware that AV systems detect. But in the real world users will often encounter malware that hasn't had time to be classified yet, and possibly (e.g. in spear-phishing cases) will never be classified. A more realistic test would include malware like that. The test writers should cover that by generating a whole lot of their own malware that's not in any database, and see how AV products perform on that. My guess is that the detection rate would be around 0% if they do it with a modicum of skill. Of course in the real world, some malware authors can and do iterate on their new malware until they're sure the major AV products won't detect it.
So for the sake of argument let's suppose 20% of the attacks in the real world use new unclassified malware and 80% use old malware and none of the 20% is detected by AV products. That would be 405 additional malware samples not detected by any product. Now Microsoft scores 77.6% and F-Secure is 79.9%. That difference doesn't look so important now.
The other major issue with this whole approach is that it takes no account of the downsides of AV products. If a product slows down your system massively (more than other products), that doesn't show up here. If a product blocks all kinds of valid content, that doesn't show up here. If a product introduces huge security vulnerabilities --- even if they're broadly known --- that doesn't show up here. If a product spams the user incessantly with annoying messages, that doesn't show up here.
Because of these systematic issues, this approach to testing actually does more harm than good because to the extent AV vendors care about these test results, they'll optimize for them at the expense of those other important factors that aren't being measured.
There are also some issues with this particular test report. For example they say how important it is to test up-to-date software, and then test "Microsoft Windows 7
Home Premium SP1 64-Bit, with updates as of 1st July 2016" and Firefox version 43.0.4. But on 1st July 2016, the latest versions were Windows 10 and Firefox 47.0.1.
Another issue I have with this particular report's product comparisons is that I suspect all it's really measuring is how closely their malware sample import pipeline matches the pipelines of other vendors. Maybe F-Secure won that benchmark because they happen to get their malware samples from exactly the same sources as AV-Comparatives and the other products use slightly different sources. The source of malware samples is critical here and I can't find anywhere they say what it is.

The false positive rate is horrendous, leading to silent and weird changes in behavior. For example a prominent AV solution stops git working under Cygwin on Windows - it fails with some weirdo error, no logging, no diagnostics, nothing to fix it. So - step 1. for all developers: disable AV on Windows.ReplyDelete
Beyond that, the number of user-reported false positives as we tweak headers and re-compile LibreOffice is beyond belief - even though the binaries, installer etc. are signed. The whole "look for virus signatures" approach seems unlikely to succeed in the end anyhow, and the performance impact of AV is severe for most low-end machines (so I'd not enable it on Windows XP either since a) you're doomed anyway and b) you ought to be able to use the PC in the small window of life you have).
I'd put good money on someone creating entirely random PE executables by shuffling code fragments of any given binary and putting them through lots of AVs of hitting truck loads of false positives; it would be great to have a comparison of the lame-ness of AVs based on that alone I guess; and some independent benchmarks of their real impact on machines.
I guess the AV industry is just another clown in the circus =)
I am so glad there are people who think the same way. I haven't used an AV for more than a decade now.ReplyDelete
I think they're the most useless piece of software in existence today that act like virus themselves by slowing down computers, interfering with other processes and the beauty of it is PEOPLE pay for them!

... I'm tempted to recommend the tool I was using several years in a row (on farm of Windows boxes at my previous job). And boy was it perfect! It's called Ariad:
If tools you mention are in the same vein like Ariad, it's very nice combo, I'd say (I used both Ariad + MSE in those older times). Because it deals more with infection causes than a consequences. Recommended!

Finally, a voice of sanity in the wilderness. I run a small IT shop and I've had people call and rail on me for hearing about me telling something this exact thing. I can confirm, personally, that I have never, not once in 20 some years of doing this, seen AV actually protect the people who were always infecting themselves.ReplyDelete
The other major issue is that by and large, the biggest problems are PUPs, which many AV solutions cheerfully ignore - or even install. Which is why in the end, prevention (patches, user education, user lockdown) and remediation (malwarebytes et al, backups, restores) have been the only thing that really works.
And yes, leave Windows Defender on.
This is a terribly ignorant article, written by someone who does not understand vectors of attack, the nature of viruses in the past decade, or anything, really, about security. It also certainly explains why millions of people are part of zombie botnets without even knowing that they are. Mind-boggling stupidity on display.ReplyDelete
Sorry, but Windows Defender is absolute garbage. Slow, poor (well, non existent to be honest) proactive features, only thing good about it is that it's easy to use since it hardly has any settings. Are you a Microsoft shill? Coz no one in right mind would recommend Windows Defender over products like Kaspersky, avast! or Bitdefender. Of which last two also offer free versions that are not any worse protection wise than their paid counterparts. Diversity in antimalware field gives users immunity. If everyone used Windows Defender, bad guys would just have to bypass that and they'd be done. And trust me, bypassing Windows Defender is easy. But if bad guys have to craft their packages to bypass 20 different products, they have to make compromises, extensive testing and even then chances are one vendor will nail them and share the sample with rest is very high. And with cloud systems, they can't test it in advance because it means AV vendors will get an insight on the malware and if they don't, they can't be sure it's not detected already. It's why everyone else is better than Microsoft, because they have complex multilayer protection systems.ReplyDelete
I was too lazy to write all that out, but yes, exactly. Homogenuity, using AV by the same company that made the OS, is insanity. In addition, Windows Defender/MSSE are simply way behind in innovative technologies like deep cloud AI (Symantec) or Webroot's tracking and reversal of suspicious application behavior.ReplyDelete
People who write such articles are terribly ignorant, and they believe they still live in an era where you could, first of all, know when you have a virus, and second, eliminate it by "scanning" after it executed.
The only thing that still works to root out modern viruses are hacker utilities like Combofix. Modern antiviruses are trying to catch up, but Microsoft is certainly way behind all of them.
This article is complete bullshit from someone who does not know anything about new security threats and attack vectors spreading in 2017.ReplyDelete
Relying on an OS and all softwares, plugins, middleswares, drivers and other stuff up to date for being safe is just non-sense.
Combination of standard AV and behavioral/sandboxing technos remain an effective way to protect from Internet threats (as well as awareness, and being up to date of course).

Since Win 95 i am used to AV Suites, and every Time it was a disaster.ReplyDelete
From slow PC, to annoying and false Messages, up to finally heavy destroyed Win OS, all of this i have seen.
The First was Norton AV because i trusted Norton Commander on Dos. This was the first mistake... later i must install Win95 new... ca.
every Year i tested another AV Programs or Suites, because most of it was free on Magazine CD/DVD... every Time was the same annoying or destroying of Software and OS (and Time).
I Think.... Why dos every PC Magazine prefer AV Suites ? it was every time annoying and slow on my Gaming PC.
Many Years later i payed many Money for Norten Internet Security Suit, and it was a better then the first Version i used, but the PC-speed was only 1/4 from before, and so many Messages from the Suit, i think ... whats going on in my PC is it infected or defect or what is it ?
I wanted to deinstall it..... mistake 2... i had to use an special uninstall program, because of the deeeeeeeeep integrating in the OS, simple deinstall destroyed my WinXP.
But i had luck, i never had a Virus from Internet. The last AV Programs i used was Free AV and AVAST..... same shit, but more annoying with activation online, messages and updating that don't real work... but better with deinstalling.
I did See a Video from CCC Germany, because how easy a PC was infected if a AV Suite is installed.
Without an AV nothing had happen, but with AV they easy become Admin Privilege and full OS/PC access !!!
Then 3 Years without AV, @2009 MSE beta message arrived, i looked, installed the Beta and tested it with an official Virus Download. MSE worked fine with download, copy and delete the harmless but real Virus. Since then i used only MSE and never had any Problems or slow PC, i never experience a slow or annoying Windows because of MSE. OK only one negative Part on MSE, if i install an old Game or Software, the start of the install is very very slow (but i don't think, that is MSE fault, its more a OS Fault with old installer Software in combination with MSE)
but this Problem dont hurt much, if i must wait a minute more or deactivate MSE temporary and don't wait.
The better Question is:
Why are here so many People that say MSE is Shit?
I can say MSE is not shit, it is very usable and silent and fast.
AV Suits are better? they Should work in a Sandbox ?(witch is ridiculous slow).
Yes there are good AV in this World, but they are very expensive and they are not in the next PC Shop to bye.
Why must a AV Suit change the Browser Software ?(this is not her piece of Software). and what if a new closed Source Sandbox-Browser arrive, how can the save the User ?
I am very satisfied with MSE since the Beta.
I am more Safe, more Speed, lesser annoying, lesser Problems with MSE + adblocker + Scriptblocker.(that dont change the Browser Software)
Thats the best every Internet-User can do, to secure Yourself !
Brain.exe is not important then...
Who else will say that an AV Suit will be better and safer for free?
In light of the recent "Avast breaking the installation of Windows 10 1803 update" I'm inclined to agree with Robert.ReplyDelete
Aside from the results of bad passwords on remote-access systems the most common compromises I see these days are...ReplyDelete
Malicious browser extensions.
Doesn't matter what OS or whether you have antivirus or not. I've not seen a single antivirus program yet capable of detecting the difference between a legitimate extension and a malicious one.
So unless your user is an idiot who believes the "you must install this codec to continue" website ads and runs things that come in unexpected email attachments from strangers, traditional antivirus does nothing. Keep up with software security updates and you'll screen out 95% of the bad stuff. Don't install browser extensions or other programs just because some random website says you should and you'll be rid of another 4.9%. The rest are things that a good antivirus program probably won't help with anyway, so it's probably not worth it.
Using something to scan incoming emails for known threats might be helpful if you get a lot of mail from John Q Public and so have to read everything. That's about it.
