AV-Comparatives is a reliable and authoritative site; IMHO a lot more than most others. They actually give full details of how their tests are done (check out the site better if you don’t spot where). They aren’t sponsored by any AV company as fair as I’m aware (weren’t last time I checked) so are ‘independent’.
The author also feedbacks to the community; he’s mentioned before that a few AV titles don’t get their results published due to hassle he’s had from their vendors - hence, if your AV software isn’t on the list then it’s a bad sign!
Until recently Kaspersky and NOD32 got the best ratings which corresponds to ‘industry opinion’. Since I doubt he’s got anything against them I think it just indicates that they’ve dropped their game a little in the latest test. I guess this is to be expected though (I recall reading elsewhere that Kaspersky missed getting the Virus Bulletin award a little while ago); as long as they recover I don’t see this an issue.
Personally, I use both Kaspersky and NOD32; former on home machine and latter on work. I’m quite happy, but have now moved completely over to Kaspersky due to getting a bad trojan at the weekend under NOD32.
I’m sure the Kaspersky rating will probably improve next time around.
