Step 1: Make sure that you have an up to date antivirus program. If you don't, install AVG. You should only have one antivirus program. (If you need to uninstall your antivirus, use RevoUninstaller)
Step 2: Visit the Google Pack website, and use it to download Spyware Doctor.
Step 3: Download and install ThreatFire.
Step 4: Make sure to use Mozilla's Firefox from here on out. Also, install the Adblock Plus and NoScript add-ons for it.
Step 5: Make sure that you have a firewall program on your computer. If you don't, install Comodo.
Step 6: Turn off System Restore, and restart in safe mode
Step 7: Launch Spyware Doctor and make sure to update it by clicking on the Smart Update button.
Step 8: Run an Intelli Scan, uncheck, "create restore point...", and then click the fix button. Repeat until intelli scan doesn't find anything new.
Step 9: Run a full scan.
Step 10: If the full scan finds something, run an intelli scan after.
Step 11: Run a full scan with your Antivirus program.
Step 12: Restart. If everything is fixed, you can stop now. If the problem persists, read my guide at the link below for more in depth instructions.
