I have a problem

hello, since I charged your antivirus avast 4 family edition when the antivirus detects a virus that starts again my PC without my opinion it is necessary to make a special adjustment??? configuration:windows XP

Strange, avast scanning shouldn’t reboot the system… maybe you’re infected.
It will be good if you can:

  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, ewido or Spyware Terminator (trojan removers).
