Melhior, I don’t know why your Avast Version doesn’t detect trojans ? But my version of Avast! 4.0 PRO finds them without fault.

Because of my intrests in Virusses and Trojans I do a lot of “testing” with multiple of them. If i’m testing, I have to close down AVAST,otherwise it is just impossible to excecute client side of trojans (offcourse i don’t install the server on my pc, i’m not crazy…) But I can’t work with ANY trojan or backdoor or keylogger if AVAST is running.

This is awsome protection !

I have used many (maybe all) trojans in the following link :

AVAST!4.0 PRO with High Heuristics settings detects them ALL.
