Hey, there, Tarq ... just a little curious. Isn't that Threatfire you're using ... an Anti-Virus? It's never caused you problems working along side avast! at the same time?
Threatfire and Avast seem to play well together. (Both apps. separately seem to get on with a lot of others, too. They're both independently and together remarkably tolerant of other valid security apps.) Although the Windows Security Centre actually recognizes Threatfire as an AV, technically its operation is somewhat different, more of a behaviour monitor/blocker, that includes malware signatures as part of its MO.
Anyway, speaking of moving Infected Files to the Virus Chest, I was wondering, has anyone ever had disaster strike after seemingly harmlessly by procedure moving an Infected File to the Virus Chest? True, some Files one can tell by the File Path / Filename that nothing or at least nothing drastic is likely to happen by moving the File to the Virus Chest. But, I sometimes wonder with the more esoteric, perplexing Files whose purpose is NOT remotely clear ... whether I'm gonna suddenly POOF! Encounter a Big Ole BLACK or BLUE Screen or No Boot or who knows what other disaster by inadvertently having moved a VERY important File to the Virus Chest. What's the risk of that happening?
I've had a minor disaster in the past, not with Avast - but I think that maybe the brand of AV may be somewhat irrelevant - and I'm not sure whether it was moving a file/deleting a file or a reg clean that was responsible.
You're not speaking with an expert, here, so I actually don't know what the chances are, but I would think they are small. It would have to be a fairly vital and far-ranging file to be deleted to give blue screen type symptoms, or similar, and I doubt any of the AV vendors would be likely to have that FP in their definitions. (As an aside, Norton did, a few months ago, and it had the interesting side effect of crippling all the Windows machines, running XP I think, but only if they were not validated (ie pirate, or not updated for quite a while), and only those running Chinese language Windows. Results can be imagined. They apologized, and put it right a day or two later. A bit late for the several thousand users who just happened to have misplaced their XP disks.)
These days I so seldom get malware that my first reaction when it's flagged is to quietly investigate the file first. Usually it turns out to be a false detection, picked up by one of my spyware scanners. Doesn't happen often. Doesn't bother me that it does. I'd rather the occasional FP than the occasional real baddy missed (if that's the choice.)
