Google Chrome Engineer Says Windows Defender 'the Only Well Behaved Antivirus', Cites 'Tons of Empirical Data' (onmsft.com) 231

Days after former Firefox developer Robert O'Callahan said that antivirus security suites are not necessary, and AV vendors are of little help. A Google Chrome engineer has echoed the same message, reaffirming that Microsoft's built-in software is indeed the most well-behaved security suite. From a report: Apparently the disdain for 3rd party AV solutions runs deep amongst browser developers, as in response to the threads a Google engineer, Justin Schuh, had this to say: "Browser makers don't complain about Microsoft Defender because we have tons of empirical data showing that it's the only well behaved AV."

    I tend to agree. I used to have third party anti-virus on the wife's machine and the kids' machine, but really the most effective malware prevention is to take away root/admin privileges altogether. Anti-virus doesn't protect against the stupidity of users. If they install malware, no anti-virus will stop them. Almost everything that the anti-virus software caught was benign and were false alarms. And despite being useless, the crap software was a resource hog.

    I have since uninstalled anti-virus. I will do an occasional malware bytes scan, but have done so less and less frequently as I find little but tracking cookies.

    So, yes, I agree with this report.

      Same here, to be honest. AVG became unusable due to bloat a couple of years ago. Avast can have some serious issues when presented with a combination of Windows 10 with Anniversary Update and a Skylake CPU. The remainder all seem to be as bad as much of the malware they ostensibly protect you from.

          Black-holing garbage domains (ad sources and trackers especially) is definitely a good idea but the problem with a hosts file is that you can't do wildcards, so while you can easily block "foo.domain.com" and "bar.domain.com", you can't block "{random string}.domain.com" unless you know what "{random string}" is in advance - to do that requires either a DNS based blocklist or some other software tool. That's getting to be a problem given that marketing/tracking companies are slowly (and it's taken them long enough) waking up to the possibilty that you can use "{random string}" as a wildcarded DNS entry to track whether a link was looked at or not just as effectively as a custom URL or cookie.

          Also, to add to the GP's comment about the importance of an Ad-Blocker, let's not forget blocking auto-run of certain browser plugins and the ability to whitelist sites that can run JavaScript / save cookies.

    The problem is that every company other than Microsoft has a built in conflict of interest. The AV software companies profit motives are not aligned with providing a good user experience. A good anti-virus system should be nearly invisible. Hard to convince customers to pony up a lot of money for security software unless you are always in their face and an anti-malware system that does this inherently results a bad product. Worse they have to keep tacking on extra "features" and products to convince customers their product is better than the next guys. Their business model is based on scaring customers so they buy their product based on perceptions rather than actually keeping them safe.

It didn't grind the computer to a halt, it didn't nag constantly, it just quietly got on with its job. In one version they went from joint last with McAfee to being one of the best.

          I use NOD AV and the only times i get bugged is when it blocks some bad resource, like a favicon or bad ad. It does not yell when it updates, I does not nag you with new versions. Set and forget and it's been like this for more than 10 years.

It's not enough of an annoyance for me to feel strongly about it.

      It is "best behaved" (for whatever that means) because it simply /does less/.

      If by "does less," you mean it is not hyperactive and so does not train your users to ignore its alerts then, yes, you are correct. It does less.

    • You're covering just one side of the problem (virus detection). Let's ignore that Windows Defender is really effective (it's close to the paid alternatives). The other side is about not raise so many false positives. Most of paid AVs raise so many false alarms that average Joe will tend to ignore the alerts or just uninstall the AV at all. Windows Defender, at the end of day, works because it has a good compromise of detection and low false alarms.

      Half the time the level of embedding IS the infection. I've never had Windows Defender cause an issue with the Offline Files service by locking the temporary files that Office creates when you hit save, resulting in the temporary files staying on the disk and the correct files going missing.

    All the AVs today pretty much catch the same low-hanging fruit, and there's no good reason to buy a third-party bolt-on anymore.

    That said, I'm getting annoyed with AV packages still not being able to flag things like base-64-encoded Powershell scripts or Office doc VBS scripts that make direct references to system libraries. Almost all the malware that's made it through our defenses in the past six months has used one of these two techniques (plus a little code obfuscation, but still), and none of the AV packages I've tested (via sites that scan against dozens of packages) have ever flagged any of the most effective offenders.

    Far too often, antivirus products follow the "cable television" market strategy:

    "Yes, we know you already pay us for a subscription, but we can get so much more out of you by forcing you to see all kinds of shit you really don't want, including adverts for all our other services."

    And, in the case of free antivirus, this too:

    "We can see that you really dont want our full package, otherwise you would have bought it instead of opting for the free version-- but we feel compelled to try to upsell you each and every possible opportunity, and wont relent at all. We will even be really obnoxious with your notification area, and make your system play audio adverts, because that's how much we really want you to have a subscription (but see the prior market strategy-- we wont let up on the ads even if you do!)"

    They invest tons of resources (both computational and time-wise) into making needlessly flashy UIs with big colorful buttons, and scary "CSI: Miami"-esque dialogs, when really--- the part that really matters-- how well they can trap execution events without bogging the system down-- seems to get nearly no love, and appears to get shittier and shittier.

    Then you have Windows Defender. It's so plain, you instinctively ignore its presence. Excepting on older XP systems, (where there was a CPU utilization bug), it runs with a very modest system footprint. It does not constantly vomit spam into your system tray, and does not try to milk you for additional service agreements, or to switch to a paid version. It behaves itself very well.

    If Avast or AVG behaved like that, instead of trying to be garishly tawdry and whorishly self-promoting like prostitutes, and reduced their system resource consumption habbits accordingly, they would win hands down.

    But no, fleecing idiots is much more profitable.

    I used to work for an AV vendor in their IT department. Others in my family have continued working in the software security industry for decades. They really are just bloated resource suckers with little value. As such, I haven't run anti-virus beyond windows defender for a little over 10 years, not even on my kids computers. They're kept up to date, ads are blocked on my network, and I have taught my kids how to recognize an executable from other kinds of files (thank god for re-enabling file extensions being shown, the stupidest Windows default of them all).

    We had one virus when my daughter opened an email that gave her some nasty popups constantly. She learned a valuable lesson that day, but I was able to reverse it in less than an hour booting into safe mode and removing the files. Been fine otherwise.

    Defender may be well behaved in terms of system utilization and other programmatic things like not install browser hooks, etc, but it has a history of being poor at actually catching viruses. Just a year or so ago it had an 85-89% catch rate. That may have improved as it has been a while since I read the literature.

    That said, no AV is a poor prospect too, especially for business. I work for a local break-fix shop that also is branching into MSP work for out small to mid biz clients. Out system uses a modified Bitdefender + site blacklisting. It works well but does have a foot print. I say it is useful though because some of our clients are 30-50 seat law firms, insurance companies, and financial institutions - you would not believe how heavily targed they are with social engineer attacks designed to install malware. Mostly through email attachments, but there have been DOS attacks, password attacks against open ports, and DNS redirect attacks.

    User training is #1, but AV and good backups have saved the bacon more than once. We see constant removals of crypto virus installers, only 2x in the past 3 years has one actually gotten through by being too new for detection. How many would that be without an AV with a 95%+ catch rate?

    • Just a year or so ago it had an 85-89% catch rate

      That actually seems really good for AV.

      No AV is a panacea. It's just one tool in the toolbox. 85-89% is a really good starting place if you ask me. Add to that DNS blacklisting, ad blocking, content filtering, application whitelisting and sandboxing, you could have near 100%.

      • by wbr1 ( 2538558 )
        85-89% is not good when competitors have above 90 and 95%. Read up on av-test and av-comparatives. I have not read for about a year, so things could have changed, but my clients are specifically targeted, plus the normal random probing and targeting that goes on. That 10% difference can be the difference between normal operations and a 1-2 day shutdown to recover a cryptolocked server from online backups. Our bill is big for that but not nearly as big as not having your entire firm run for 1-2 days.
        • If your clients are specifically targeted, no AV is likely to catch the attacks. AV is there to catch the low-hanging fruit, not the ones coming after you specifically.

    • From what I could see in a few different tests windows defender is about 97% and there are a few scanners that go to 99.9% but the higher the detection rate the more likely it also is to suffer from false positives and impact the system negatively while running.

    I had bitdefender installed on my machine about a year ago and I was writing c++ HPC software. Everything was compiled with the Intel compiler and mkl with profile guided optimizations. Bitdefender started detecting my binaries as virus infected and deleting them. This happened a few times and I disabled it for a month and later turned it back on with newer virus definitions and the same issue kept happening. It even detected some of the binaries I had on a shared drive and deleted them also.

    The false positive rate on some of these scanners is just too high.

    I will just stay with windows defender since it has not interfered with any of my debugging or profiling and has never deleted the software I am compiling.

  • Strongly suspect the main reason the browser developers like Microsoft Defender as a "well behaved" AV is because it's purely a file level defence, and so doesn't interfere with the behaviour of the browser. Unlike many third party AVs, that will intercept internet traffic, looking for bad stuff before it hits your browser.

    That's good from a browser point of view, because they don't have to deal with browsing problems being caused by the AV engine (for example, without whitelisting, ESET's engine will cause

    I read the entire thread up to my standard filter level, and this is what I concluded: the singular of anecdote is "one size fits all".

    It's pretty clear from what I've read here that for a low-value target, I'd just settle for the low-hanging fruit of Windows Defender, ad blocking, a DNS block list, etc.

    It's also pretty clear that for a high value target (e.g. law firm, bank) where the minimum system install is a bulked-out i7 I'd elect to suffer the bloat & obtrusiveness in order to obtain the somewhat better catch rate of a first-tier third-party solution. The people working for these kinds of institutions are pretty demoralised to begin with, it will just look like business as usual (and so it is).

    The other side of this is that "one size fits all" is directly connected to the competency porn carapace. "Well, I work for banks and law firms and YOU can't handle the truth". But what actually gets written is this "YOU can't handle compensating my clients for a 48-hour loss of service". This tends to be a person whose amygdala has swollen to such a painfully large size that he or she can no longer multiply 1% times 365 (the constant friction of a badly behaved "solution") and can only multiply 100% times 2 days (as specified under the total availability-loss Weimar Reparations Act).

  • Someone has obviously not used BitDefender.

  • I haven't run any virus checker other than the one built-in to Windows for years now. They all catch old or obvious viruses. None of them is going to catch a new, clever virus. There's not a whole lot in the middle. Add in the virus-like behavior of the AV itself, the performance-suck of most of them, and it just doesn't make any sense to use them.

    As another poster pointed out: user error is the biggest cause of virus infection. Train your users, use Windows Defender as a sort of "sanity check", make regula

  • I have a strong instinct to take it with a bucket of salt when a stranger on the internet tells me "oh yeah, you should ditch your AV."
  • I've been running my company on MSE/FEP/Defender for the past 6 years with zero headaches caused by the anti-virus software itself and an infection rate of maybe 5 or 6 per year across 200 PC and laptops. Users have local admin rights. Perimeter IDS catches some things that get through.

    It seems to work better than any other anti-virus I've used and I hate them all. It's certainly the least annoying.
  • Antivirus software is a hot topic in IT security right now. Not because you need AV, but because most AV is terribly designed and breaks security in other applications. And while Windows Defender may not score particularly well on canned tests used by AV reviewers, it doesn't break as much software as other AVs do.

    Remember that in order to work, AV has to inject itself all over the place in your system to intercept network activity, disk activity, etc. But if it does that at the expense of other security

  • Most AV software is bloated crap that offers little actual security.

    Microsoft has been focusing on power efficiency and battery life, so I'm not surprised if they traded off a little detection capability in order to run smoother.

    Antivirus isn't even on the top of the list for avoiding an infection. That would be (1) don't browse as admin, (2) keep software updated, and (3) use an adblocker or filtering proxy.

    With the vast majority of malware being drive-by downloaders, a good adblocker or filter offers more

  • AV software for anyone that has had to use it for any amount of time can easily tell you that Windows Defender is the *only* AV software anyone should be using anymore. Back in the day, there were a number of products out there which I would call good. Now, probably due to increased pressure for more profits, subscriptions, and increased monetization of every aspect of their business I wouldn't want any of them. Not only are they all bloated resource hogs, they cause more problems than viruses they catch. I
