    Re: Impact of security software on system performance investigated

    Quite struck by the number of posts on this thread from folks using multiple products, with MalwareBytes being popular, wonder if it's worth paying for that? (I've got the free version backing up my McAfee install).

    I'm usually pretty sceptical about these website based AV comparisons because usually the website has a preferred product that they'll give top spot to.

    Career status: still enjoying my new career in DevOps, but it's keeping me busy...

    Would personally say you really can't go wrong with Malwarebytes, I'm running pro Malwarebytes with free Avast and to be fair I think its Malwarebytes doing the brunt of the work (though again, common sense means it very rarely has to do anything anyway). Its less of a great deal now its subscription based rather than lifetime license however, but still worth the price I think.

    I've used Avast for many years, such a great product.

    Between my Macbook Pro and my own 280X equipped desktop, I notice no noticeable difference between the speed of the internet. I don't use any AV programmes though. Not even Windows Defender.

    No one product is 100% - it's doubtful that multiple products together are 100%. If they were, they'd be so invasive that your machine would drag to a halt. This poll isn't showing any kind of efficiency in actual virus/malware protection - just the footprint the product has on the system. Apples and oranges. And you are correct about the bias factor - it's huge across the board. I can't remember if it was MaximumPC or PC Magazine that had the nerve to put Norton Home at the top of the chart one year, with an incredibly small print disclaimer about being paid to do so, but since that point, I pay zero attention to any once print now digital publications on the subject (or pretty much any other 'review/comparison').

    The biggest issue these days, especially to the home user, isn't virii or trojans or the like - it's the new age malware/0day stuff, usually brought in from e-mail phishing and Flash vectors - stuff that can generally be caught and managed via MalwareBytes alone. A small footprint A/V with excellent heuristics is all that's needed for virus control. That, and the common sense to not click on executables and certain types of spreadsheets, etc, from people you don't know. As far as the Flash issue goes, simply uninstall it and use HTML5. Unless your business absolutely demands it, uninstall Java while you're at it.

    But as with all things, the more any product claims to do, the less it will do well overall.

    @aniilv `im still using defender tho but only because i cant disable it on windows 10 because its mandatory there -_-`

    sorry mate, go to `settings/update and security/windows defender` you can turn it on/off there.

    Re: Impact of security software on system performance investigated

    I find it interesting that there are no studies on the performance of impact from various virus, trojans, spyware and other malware attacks on a system. I would have thought that the small performance hit from running a security package would be well worth the protection when compared to the potential performance hit of falling victim to a threat and that's before the risks of data loss, invasion of privacy or other stability issues with the OS are considered.

    Pretty sure every article ever done pretty much says that malware is bad (I'm not sure there's been a real virus, in the wild, in years - discounting Stuxnet)... interestingly, it's only the most obnoxious ones that have any real impact on the home system, such as bitcoin miners. The lightweight stuff, like keyloggers, etc, have almost nil for a footprint, and unless you are specifically looking for them, they don't show up in 99% of the a/v products out there. You need a specialized product.

    Programs like Kapersky can be set to do deep packet inspection, which is no big deal if you have the horsepower and internet speed to ignore it. An even slightly lower spec'd machine on the typical slow US internet services can bog to a standstill. Another common free one, Panda, is a resource hog regardless of system age. Norton.. McAfee... even AVG. They all use whatever resources they feel they are entitled to, often to the detriment of the user.

    If you look in the Java control panel, you can turn off support for java in the browser. That eliminates the regular drive-by infection threats that it is famous for.

    Our local rubbish tip has a webcam that requires a java app to see if you will be queueing if you go to dump stuff. I think that is the only legitimate Java app I have seen in years, I don't miss it one bit.
