hi i was wonderin if my comp is infected becuze ive been noticing that when i dl with firefox all my downloads are corrupted. when i try installin it or opening it sometimes it works and sometimes doesnt. when i open the file the .exe it begins to install itself normally but durin the installation it would say error blah blah corrupted file when its nearly done or half way and at times it says the file is corrupt when i just open the newly downloaded file. But after i clean out cookies, history and cache on firefox i dl the same file again it works fine. could u guys help me, fix this problem?
