It is always better to depend on system restore so that un- identified errors are undone with out affecting the basic operating system. I suggest that you try to carryout system restore to a day previous to the day when there was no virus or any problems. 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

The problem is likely to be solved. Then,You insatll a standard antivirus soft ware such as Norton, AVG , Avast ( free antivirus software and Ad-aware, Ewido ( free spyware removers). You can download free softwares at
