Is it the unzipping program that it alerts to in the window, or the actual zip files that it alerts to?
Basically what is in the alert window?
What version of avast, and windows etc?
Free Avast version 6.0.1000 and Windows XP.
Most of the time it doesn't give any alerts. Just double clicking on a zipped file hangs the computer. I do not remember the exact wording in the pop up message, but in the couple of few times when the pop up box appeared, it says something like, "Avast detects a potentially harmful file that you are trying to open. For your safety, Avast recommends it to be opened in Sandbox mode."
And there is no option to open the file properly and override the Avast sandbox, it just has a Yes/OK button.
Once you click that Yes/OK button, the whole computer hangs.
Now I have the real time Avast File System Shield stopped completely. The Avast suddenly seems to think that
all zipped files are potentially malicious. I don't know why this happened, because it was alright before this. No problems with zipped files before this, and I did not change anything with the Avast settings either. I never bothered about it but it always did its job. But now, it is a royal pain in the as* if you know what I mean!
It's crazy, I tell you.
