In the Malware and Spyware Cleaning Guide the Homepage link in the following does not work. I just wanted to bring this to your attention.
TFC (Temp File Cleaner) - Download - Homepage
Why? This will remove unneeded temporary files from your system, make automated scans that follow run faster, and save you time. Many infections also load from a temporary file location.
Download TFC to your desktop, or other location.
Save any unsaved work. TFC will close all open application windows.
Double-click TFC.exe to run the program.
If prompted, click "Yes" to reboot.
Save your work. TFC will automatically close any open programs, let it run uninterrupted. It shouldn't take longer take a couple of minutes, and may only take a few seconds. Only if needed will you be prompted to reboot.
