Need more Disk space or getting weird viruses? You need to Delete ALL the files in this folder at lease once a month.
There may be a few files that you cannot delete. See image below.
Just hit "Skip".
If you are unable to see this folder, "AppData", under your UserName,
Goto your "Control Panel"
Select "Folder Options"
You will see a window like this pop up.
Then select "Show hidden files, folders, and drives"
