I have been having this problem for several months, and can't find an explanation anywhere. Many times, after downloading an installation program (most recently AVG free, but this is just an example), when I go to install, I get the msg "File is corrupt" and installation halts. It seems to happen a LOT with AV software (but does happen with other types of software, as well)...I have vainly attempted to install KIS and KAV, NOD32, Panda, and others, but every single one of them fails to install. When attempting the install for AVG, for example, I tried to install a half-dozen times...but the installer stopped at a different unpacking percentage each time, ranging from 18 to 97%. This makes NO sense to me, because it seems as though if a particular part of the file was corrupt, it would stop at the same point each time. What could be causing this? Befuddled and confused
