i don't think the fault is actually with the avast product because it never even notified me that it so much as noticed the hack being present on the computer at all.
when you run the hack itself, the hack immediately complains about avast before you ever get the chance to add an exclusion or fail or perish in flames. never gives you a chance to try even. pretty short explanation, considering you're expected to cut your losses on a mainstream, paid and not to mention pretty damned necessary piece of software. flush forty bucks?
