I downloaded the eicar test virus, and Avast prompted me to choose an action. I clicked "more info", and avast crashed. after waiting for a bit, i tried to close the warning prompt, but it wasnt responding, so i had to force it to close. the eicar test file then downloaded to my desktop, and i was able to open it!!
I tested this on my desktop pc also, and the same thing happens.
Im using the latest version of avast, xp home (laptop) and pro (desktop pc).
