Roidelstein,
Once you follow the steps of the article in the thread:
Guide for Eliminating Spyware, Adware, and Random Popups
If you still have problems we will take a look at your system using the program:
Hijack This!
If you use it, do
NOT repair anything, just scan your system and post the results found in your log file. HJT! finds everything in your system, good and bad, we do not want to "Repair" anything that is supposed to be in your system.
Take Care,
Richard
