many, many, MANY corrupt installs

Hi everyone--

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 --

Malware could, I suppose.

Especially so if all the programs are related to security of your computer.

If the problem extends beyond such programs...then it could be hard drive or memory problems (just a guess).

In any case, it's not normal, expected behavior by the system.

You might consider doing a couple of online scans of your system.

You can try some of these free online scanners to see if anything has slipped by your protection:
(Be advised that some of these scanners will pickup things in "quarantine" from other anti-virus programs - so review the results carefully)

If you find that you're infected (or the scan doesn't complete or closes unexpectedly), post in the Am I Infected forum located here: http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/

Well hamluis has said it all, but just another simple thought

Open Start Menu > Run
Type : chkdsk /F C:
when asked press Y to scan C: drive on next boot. Do this for all of your partitions.
Reboot and check if you can install now.
