Hi everyone, I recently did a clean install of Windows 7 onto a new hard drive, and have been having several problems that I don't think are malware related. I've already done a repair install via upgrade media, and some problems that I had before went away, but many of them remained. My internet repeatedly crashes. Firefox started off fine, but the crashes got more and more frequent until now it crashes right when I click it. Internet explorer doesn't crash nearly as often, but it does occasionally. After I installed Microsoft Office, I tried to "Activate by internet connection", but it told me that I couldn't because I don't have an internet connection, even though my connection is perfectly fine. I also have a problem extracting things, usually when installing. Often if I try to install something like firefox with the setup.exe, it crashes during the extraction stage and says "Data error", "CRC error", or "Files corrupt". Windows explorer crashed 1 or 2 times for no reason, and some programs like Dolphin emulator crash as well. I tried to attach a Hijackthis log file, but it told me that it was an "invalid file" <<?? Any help is greatly appreciated!
