Hello Rezinus ,
Are all your othwer scans coming up clean? This is easy to resolve if this is indeed the only problem.
Click Start Menu > Run > type (or copy and paste)%SystemRoot%\System32\restore\rstrui.exe
Press OK. Choose Create a Restore Point then click Next. Name it ( something you'll remember) and click Create, when the confirmation screen shows the restore point has been created click Close.
Next go to Start Menu > Run > typecleanmgr
Click OK, Disk Cleanup will open and start calculating the amount of space that can be freed, Once thats finished it will open the Disk Cleanup options screen, click the More Options tab then click Clean up on the system restore area and choose Yes at the confirmation window which will remove all the restore points except the one we just created.
To close Disk Cleanup and remove the Temporary Internet Files detected in the initial scan click OK then choose Yes on the confirmation window.
Scans should now come up quiet.
Let me know how you come out.
