[Toms] Do Antivirus Suites Impact Your PC's Performance?

Most of us are now fairly confident that our antivirus scanners are doing their main job of protecting our systems from malicious pests. But what are those scanners doing to system performance behind the scenes? Are some scanners better than others?

Kaspersky is very secure but horrible at the same time. It slows down your PC. I think MSE is best and nothing can surpass it. Its detected each and everything.

i feel like avast is big enough and should have been in the comparison, but hey.

anyway, avast uses less resources than steam or origin, so i have no worries about it gobbling everything up.

Use high end processor too expensive for most people to afford then conclude that processing useage doesn't matter anymore as a generalisation.

I would have liked to see some indications of memory usage for each product, there seems to be alot of caching going on.

The webpage load time was the most interesting and surprising to me.

However, I am sad that they focused on CPU load as the primary emphasis of the study as opposed to hard drive usage, since the hard drive is by far the rate-limiting component of most current computers (as even stated in the article, CPU's are "so" fast these days, is it even relevant to discuss the toll AV programs have on them?). It would have been nice to see some more hard drive-based results. I know for sure, when my work laptop (running a symantec AV program) is doing the scheduled weekly scan, good luck getting MS Word to open in a tenth the time of what it normally does--and that's even with superfetch enabled. Another program that isn't accessed nearly as often? Might as well just wait until the scan completes...

Anyhoo, I use Avast for my personal computers. I honestly have no idea as to its "secureness," because I never get notified that it's caught anything, but I also don't notice any slow-downs. And to be honest, other than real-time protection, I don't have it do any scheduled "deep" scans, but I also don't practice poor internet usage that would enable getting a virus or malware, etc.

Yet another toms article that misses the point, HDD and RAM bandwidth are what should be checked.

Not sure how a 2600k is beyond the reach of most people, not like we're talking about a 990x CPU is it.
