do a system restore to a previous time prior to the virus. and i assume you did not just scan your machine. just scanning it will not remove the virus...

Best thing I found for this is called FIXWAREOUT. Google to find a free place to download it. It worked for me.
during the process of deleting spywares some errors might have occured. When ever unknown problems like this occur, carryout system restore. Restore the PC 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. It is easier and mostly your problems will be solved.. If you want to know an effective procedure for system restore please visit the following site.
