Couple of problems I'm having with even the latest pre release 5.0.492 Home/Free edition AV.
1. Scanning a large file by right clicking on it, say 1.25GB in size. I know that Avast most always sees one file this size as a Decompression Bomb and therefore, doesn't scan it, but few seconds into the scan, pops up the warning, error...this is a decompression bomb. So exit out of the popup window at the top right, crashes Avast.
So here is the window when it first crashes..
Then clicking on that Close the program, pops up again with second window. Then it finally exits out of avast.
2. Something that has been happening for a while with builds.
Downloading something, from Firefox let's say, and if I right click on avast icon, and disable all shields, it will disable them, but cut off the download. In other words, the download will stop short and finish, even though it's not finished. Why does this happen? It should not in my opinion.
3. After disabling all shields, then turning back on again, the right click context menu scan on any files, does nothing. No action is taken. Have to reboot, in order for the right click scan to work again.
Hope it will be looked into.
