Hi Frazhm,
Please download 'Hijack This!' from
here, unzip, and place it in it’s own folder, (not in the temp folder, or on the desktop) doubleclick HijackThis.exe, check for updates by clicking on
Config | Misc. Tools | Check for Updates and follow the prompts. Once updated click on
Scan. When the scan is finished, click "Save Log", and copy and paste it in a reply.
This will give us a rundown of what’s going on in your PC. One of us here will be glad to analyse it for you.
Don’t fix anything yourself yet, as a lot of the stuff on that list will be harmless or required.
Cheers
Liam
