McAfee quarantines svchost.exe on millions of WinXP machines worldwide

Just another nail in the coffin of the usefulness of AV systems. And good riddance.

My work computer actually has McAfee on it, which I've disabled through the registry. Don't like how slow it makes my computer.

Education, people! It's better than buying useless feel-good software.

With fake SSL certificates signed by "real" CAs, cross-site scripting and other advances in phishing attacks, just educating users may not be as effective as it used to be. Malware is quickly becoming advanced enough that even trained technical users may be fooled. Many attacks don't require user interaction. AV products may be slow to respond and signature matching won't catch everything, but if it catches half of what shows up on corporate networks it can still save a lot of time and money.
