I say this with the utmost respect for you guys' knowledge and experience.
We know, this is a discussion, the idea of what is to get your opinons voiced, so no offence taken

Anyway,
Never heard of disk imaging? Test a program on a infected hard disk. See what it cleans up. Restore the disk image and try another program.
Good point, didn't think of that.
Testing anti-virus programs against real malware is fundamentally pointless? Oh, come off it!
I didn't say that, i was saying that making a decision on a AV's detection rate by using 0.03% of all known malware is fundamentally pointless (using my example anyway).
Avast! provides a perfectly good level of protection and detection. The few things it does miss it probably catches a few days later. (I used Kaspersky to clean up a new variation of Codbot which Avast! couldn't touch last week. The next day a new definition came through from Avast! for a Codbot variant. Betcha that was the same one!)
I would of agreed with this anyway, its a logical statment.
But anybody who claims in the face of ALL the tests and reviews published of anti-virus programs that Avast! has the best detection rate or is the best anti-virus program is living in cloud cuckoo land.
I didn't say it is the best, there is no 'best' scanner, they all find and do different things, anyone trying to find the 'best' scanner is 'living in cloud cuckoo land', again, my opinon.
It's like saying a Skoda (another fine Czech product I believe) is better than a BMW. Nobody will believe you. Tell me you drive a Skoda because it's more economical, more practical around town, has more character, is less likely to get nicked and anyway most BMW drivers are knobheads and I'll believe you.
Depends on what kinda cars you like, same can be applied to anything.
In my opinion, such a test like this (even the most respectable Virus Bulletin, ICSA Labs) almost tell nothing about the "real-world detection" of an antivirus software.
True, i actulary liked
FastGame's way of testing an AV, this to me is the most logical and scientific way.
Norman Sandbox desperately depend on proactive detection such as so-called heuristics.
Never really liked the idea of relying on heuristics myself.
Avast can be very fast to response to the major malware but also slow to some lesser priority malware.
Mostly true, but overal the detection rate is still very very good, or it would be pointless using it.
