+1 buy a mac for all your horse porn needs
But I use
www.spywareterminator.com <- 100% free
CCleaner (google's your friend) <- also 100% free
*Important before you start
- If there's ANY antivirus currently installed (trial, full, expired - whatever), it MUST be uninstalled first. More than one antivirus program, and they can actually inhibit eachother. I know some antivirus programs like Symmantec/Norton actually have an uninstaller program to remove the antivirus (all legit, off of their website, to prevent viruses from removing the antivirus programs) - So make sure you rid your computer of all that shit before even attempting to run spyware/ccleaner.
1 ) Boot up
2 ) Disable System Restore
3 ) Reboot into safe mode
4 ) Run full-out scans with both programs listed above
5 ) Once done, reboot
6 ) Verifiy you're good
7 ) Re-enable System Restore
8 ) Create a new Restore Point, while deleting all old ones.
Hope this helps brother, good luck.
