Sorry ppl!
I just gave the link cuz avast is not detecting some of them. So i thought it would help!
So then why don't you remove that link?
This site is well known to people that collect viruses/malware as a hobby (virus collector) and I'm very very sure that ALWIL knows it well.
Avast is not necessary to detect all malware in this site coz most of them are so-called zoo malware, e.g. old DOS viruses, malware that never succeed at spreading or corrupted samples so they are there for collecting and trading purpose only!.
Except Avast wants to be a winner in such tests as Kaspersky always be.
