Firstly update and run your anti-virus product. You can also run a free online scan as well as some malware can actually corrupt or disable your resident security products. Here are a few online scans you can run:

Trend - http://housecall.trendmicro.com/

Panda - http://www.pandasoftware.com/products/Ac...

Norton - http://security.symantec.com/sscv6/defau...

Second download, update and run scans using the following products:

SuperAntispyware

http://superantispyware.com/

Spybot S%26D (free version requires manual updating)

AVG AntiSpyware

Adaware from Lavasoft (free version requires automatic updating)

(These programs can be run in Safe Mode after downloading and updating)

Third, after cleaning your system, disable System Restore, reboot and re-enable System Restore when you log back on. This will clear the malware that may still be lurking in System Restore, which could be reinstalled should you need to rollback at some point. Additionally, a reboot may be required to complete the malware removal process.
