suggest what to do...
thank you

Try this, using Internet Explorer go to:

Free Virus Scan - Free Antivirus Software | Norton Security Scan

Click "Continue to Symantec Security Check", in the next window click No when asked if you want to close this window, that will bring you to a window where you should click Virus Detection.

Write down exactly anything it finds, then go to: : and do a search for what was found. Symantec usually has a removal tool and/or directions for removing manually. Make sure that you follow the instructions for removal, step by step, especially the part regarding disabling System Restore.
