This is what I have been told to Delete to keep Bugs & Spy's from my PC.
All Prefetch files
The Auto clear private data pop up thing.
C;\,Documents and settings\ my name file\local setting\ temp. And to delete all in that Temp file.
But I have stoped doing that because I now have missing files.
The biggest problem I am having is if I place a fire fox Icon on my desktop from a downloaded link I have saved.
When I go to click on that Icon it cant find that link, I get an error popup.
So should I be removing these files.
Or should I let CCleaner remove them for me.
