I been trying to fix my computer for the last 24 hours, I haven't even sleep. I already format the Hard Drive and reinstalled Windows XP again. My probem was that the computer kept shutting down by itself, but after all I did, that problem is fixed. however my results from Google are still been redirected to other websites, so I decided to install Avira. I ran into the 8 steps you guys provided to solve this problem here: techspot com/vb/topic58138. I already downloaded the CCleaner, the Hijackthis and the SuperAntiSpyware Home Edition Free Version, but for some reason Internet Explorer will not let me download the Malwarebytes' Anti-Malware. I'm about to run the CCleaner.
