Try using System Restore. Go to Start%26gt;All Programs%26gt;Accessories%26gt;System Tools%26gt;System Restore. Restore the system back to a point before your installation. Bear in mind that any programmes you've installed since the date you restore to will be lost.

Before then, be sure to have tried using Control Panel%26gt;Add/Remove Programs.

I suggest that you try to carryout system restore to a day previous to the day when there was no virus or date of installation of the virus programs. It may be a few weeks or months back. You have to decide the date. Detailed instructions are posted at http://fixit.in/systemrestore.html
