Have you run the Windows' Disk Cleaner and Defragmentation utilities? After starting Disk Cleaner and letting it complete its population and before actually running it, select the Options tab and run the clean old restore points option first. Once that completes, it will return to let you finish the Disk cleaner operation. Make your choices of what you want cleaned.
You also may be severly infected with malware. If running Disk Cleaner and Defragging the hard drive doesn't help, then I recommend going to the Malware section
of this forum and follow the instructions at the top. Especially the Malware Removal Guides and Tutorials
page. That will give you several steps that will help you clean up most of all problems by yourself. If at the end of the cleanup process you are still having difficulty, and you may not be, then post a hijackthis log in THAT forum.
Please be patient as the "Malware Forum" is a very busy place and a two or three day wait is not unusual.
If you are still having problems after getting a clean bill of health from the Malware Section, please return to this thread. Please do not post a HiJackThis log in this thread unless asked to do so and then only as an attachment.
To attach log, when requested, either change the .log extension to .txt, or put the log into a compressed (zipped) folder.
Please post back if your problem has been solved.
