What is your OS ?
What is popping up the alert ?
Can you post a screenshot of it ?

I suggest you remove your email address from a publicly available forum unless you like spam.

If a virus is replicant (coming and coming again), you should:

  1. Disable System Restore on Windows XP: http://support.microsoft.com/default.aspx?scid=kb;[LN];310405
  2. Clean your temporary files.
  3. Schedule a boot time scanning with avast. Start avast! > Right click the skin > Schedule a boot-time scanning. Select for scanning archives. Boot.
  4. Use a-squared, Free AVG Antispyware, SUPERantispyware or Spyware Terminator (trojan removers).
