Well Sarcastikus you have a pretty major infestation going on there.
Go to Add & Remove Programs and remove any Toolbars & Search items that you did not knowingly install.
It may be that after all this is done the scumware my reappear, if so a HJT cleaning may be necessary. Repeated scans after rebooting will tell you if they keep reappearing. Read these instructions if a HJT cleaning is needed and post the log to the appropriate forum.
After doing this and the problems are not better feel free to post a HJT log.
Be sure to read the How to submit a HJT Log
and submit it to the appropriate forum. HJT Forum

Then disable and re-enable your system restore.
This will clean your restore points. Nasty stuff can hide in them.
This is not an option in Win98.
I sometimes forget what OS & forum I am in also.
For future reference it is not a good idea to delete the restore points until you are sure the system is clean. I feel it is better to have an infested restore point & not need it then to need a restore point and not have one should something go wrong in the cleaning process.
