This are the most common tasks necessary to keep your PC free of spyware
Oh No -- you just clicked that executable and the spyware is all over your PC.
Here´s what to do.
1.- Admin your mistake. Pledge never again to click "YES" when an IEpop-up window says, "Your system might be compromised!!! Repair now?".
2.- Check the Add or Remove Programs control panel for anything suspicious. Only the friendliest spyware/adware programs will show up in the control panel, but it´s the most reliable way to remove anything that dows, as anti-spyware tools tend to leave some scraps behind. Remove anything that´s suspicious. If you have trouble with the removal, try the same procedure in Safe Mode. (Running in Safe Mode is good advice for any of the below steps. Because Safe Mode runs only absolutely necessary apps, you may have more control over a badly infected system.)
3.- Run a complete antivirus scan. Make sure your advanced scanning options are set to the highest level of protection. Scan inside compresed files and turn any heuristic scanning options to maximum protection.
4.- Run Spybot Search & Destroy (one of the best anti-spyware programs and is freeware http://www.safer-networking.org) after updating the program definition files. It may require several reboots to flush out all the spyware in a computer seriously infected.
5.- Run a second anti-spyware scanner, such a

This will help eliminate any hiddenn apps that Spybot didn´t catch.
6.- If you´re still infested, run HijackThis! to generate a log of active system processes. If you can´t interpret the log with the help of online searches, post your log file at http://forums.spywareinfo.com with a polite request for help. Someone will usually respond within an hour, advising you on wich entries in the HijackThis! log you should disable, or what custom removal program might help your case.
7.- If you´re still infected, fire up Windows System Restore, and roll your system back to a distant checkpoint from a time before your PC was infected.
8.- If spyware keeps popping up, you are probably hosed. Your best bet at this point is back up your data files, and wipe the drive, reinstalling Windows from scratch.
Be smart and good luck.
