right... they were ALL out of date. Still, what's the point? If you can browse the web and potentially get malicious software installed on your computer, then why would you have out of date definitions for your virus database? I mean, if you're browsing the web, then your A/V program should have access to the internet too, and it would have updated itself by then.
The only reason avast may be low on the list is because the definitions were out of date, and it doesn't use heuristics to find "potential" viruses. If it doesn't know about them, it can't detect them.
I think it's just a dumb test. It doesn't prove anything, other than how many new malwares have been added since the last time they updated the definitions on the test computers. So what?
