Even after taking all these precautions if your computer does get infected, then here are a few things that you can do:

Online clearing tools - are a good source of trying to clean out virus, there are many Anti-Virus websites that offer free online virus detection and removal services.

Removal tools - If you have an Anti-Virus software then you can go to website of that software and download removal tools designed specifically for virus. However, you must find out name of virus that infects your PC beforehand.

If you have a backup of all your important files, you can also consider formatting your hard disk.

Win32/Berbew - Moderate* Win32/Doomjuice - Moderate* Win32/Gaobot - Moderate* Win32/MSBlast - Critical* Win32/Mydoom - Moderate* Win32/Nachi - Critical* Win32/Sasser - Critical* Win32/Zindos - Moderate*

* The severity rating refers to virus alert severity ratings that appear on following Microsoft Web site:
