Bring your antivirus program up to date and regularly do a full virus scan of your computer. Check your antivirus program as it will tell you when the last full scan was done. You may be surprised to see it is not what you thought, but was done months ago.
If you don't have an up to date antivirus program, and don't want to pay for a new one, there are several high quality free ones available to the private consumer.
They are: AVG, Antivr, avast, PC Tools antivirus, Comodo antivirus and the open source Clam AV.
Also look into a new different kind of antivirus program ThreatFire which you can use to supplement your other antivirus. ThreatFire doesn't look for the fingerprints or DNA of known viruses. Instead it looks for suspicious behavior like key logging.
Also try the no longer free WinHki Anti-Virus, which acts as a supplement to normal Antivirus program like above. WinHki calculates the checksums ( a mathematical calculation extremely difficult to fool) of your files on initialization.
After that, whenever a virus changes a file it will be flagged by WinHki because the
check sum will change.
