  1. Restart your computer
  2. After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually; Instead of Windows loading as normal, the Advanced Options Menu should appear;
  3. Select Run Windows in Safe Mode, then press Enter.
  4. Then scan your computer using an updated Antivirus.
  • SCAN FIRST! Each and everytime you insert a USB drive/flash disk on your computer don't forget to scan it first. (Given that your Antivirus is up-to-date).

  • TechGuy - this site is full of information about removing malwares (you might want to search first to minimize the hassle in asking for help-maybe you're not the first one to experience such tragedy)

NOTE: To further maximize efficiency,
  • You should install HijackThis (product info is on their site).
  • If you download the Executable version please make sure to place it in a permanent folder. HijackThis makes backups of anything fixed and the backups might be deleted accidentally if the program is run from a temporary folder.
  • Run HijackThis, click "Scan and Save Log", and save the logfile produced. Please do not fix any entries with HijackThis unless a helper tells you to. Most of the entries in the log will be legitimate, or even critical to the operation of your computer.
  • IMPORTANT! The log file is the one that you will post to these sites so that the malware expert can diagnose the situation..
