Zdnet is the most un-credible source of Reviews out there. Not only does Zdnet not even use their own samples for testing, they lack technical knowledge to even be considered credible review sources. Not that i'm a technical guru, but my god, they are newbish beyond belief.
For example:
"In past VirusBulletin tests, Trend Micro's PC-cillin has been tested on Windows systems six times since November 2001 and earned its coveted VB 100 percent title five times. By comparison, Norton AntiVirus has been tested on Windows systems six times since 2000 and passed each time; McAfee VirusScan has been tested and earned the coveted VB 100 percent title only once. "
So apparently, they think they can credibly recommend a product based on someone ELSES testing? That makes no sense to me whatsoever. Secondly, Virus Bulletin is nothing more than an indicator of relative ITW performance, but by no means is real world. Even 1 false positive disqualifies many people, so the details must be closely examined. Any reviewer that uses VB awards as a method to add credibility to their own reviews, deserves no mention at all in my book.
A more reliable test - if you exclude his DOS virses, would be:
http://www.av-comparatives.org/Which as you can see, Avast scores a bit higher than Trend with the on-demand test, and comparing that to my own personal inhouse testing, he's pretty acurrate. Oh, and look at McAfee's scores here, compared to the other products listed... I don't run McAfee personally - and I probably never will run it, but few can deny its raw effectiveness with detections.
So your short answer: Avast is better than Trend.
PS: I don't see how you read into my first reply as a flame.. I just don't see it at all. You asked a question, and I answered it. The only thing I questioned, was your "Assumption" that everyone else thinks McAfee and Norton are lacking. Thats just not the case. Hopefully with my post, you'll be armed with more knowledge, allowing you to make an informed purchase decision for your AV product. Good luck.
