Virus of pop ups?

[Surfn]

Here's an easy fix if you have XP, Chop can verify this because I helped him when his OS was trashed.

1) Click on start
2) Click on accessories
3) Click on system restore
4) Choose a date prior to the start of your problem

That simple it will kick you OS back where it was. Any new files or data created will be there it doesn't delete what YOU create. HTH
