Reinstall Windows. Then get some real security to keep it infection-free.

Good security requires a multi-layered approach, and the least important layer by far is running some kind of anti-malware program (in fact, if you take care of all the other layers, you don’t even need an anti-malware program using up extra resources).

In order of importance:

1. Create and use almost exclusively a limited user account instead of the default administrator account Windows sets you up with

2. Read up on social engineering and how to avoid it

3. Don’t download illegal copies of software, music, or movies

4. Set Windows updates to install automatically

5. Make regular backups. If possible, back up your entire installation (using Norton Ghost or Acronis True Image)
