Hey guys! As you may notice my name is Gustavo. I got to this ofrum for help. 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 fix. however my results from Google are still been redirected to other websites, so I decided to install Avira, I'm actually running the scam right now, is going about 7.1% and already found a Trojan, it's called TR/Crypt.ZPACK.Gen like 3 times. Avira says that it cannot be removed, so it was put on Quarentena. SInce the scan still running I have been trying to find other ways to fix the Google issue, so I ran into these 8 steps you guys provided 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 waiting for the scan to end to see go to step tree and run the CCleaner. Thanks guys for the help you offer, it's very valuable.
