Hello peejay,
Please uninstall HijackThis - the version you are using is out-of-date.
Download Random's System Information Tool (RSIT) from
here and save it to your desktop.
Doubleclick on RSIT.exe to run it. Your computer will be scanned and once the scan has finished, two logs will open. Please post the contents of both (log.txt will be maximized and info.txt will be minimized) in this topic. You can also find the logs in the C:\rsit folder. The logs will be reasonably large so you may have to divide them into sections and make several posts to post them.
