I dont know what kind of programs you are using to rid your computer of junk but try this. Right click Internet Explorer on your desktop, select properties, select "delete files "and select "delete offline content". then in that same window, delete cookies. Then try a program called "Crap Cleaner" found
Here and click the top right corner where the arrow is saying "download latest version". Install the program and run it. Click "run cleaner" and allow it to create a backup if it asks to. Then click "Issues" Scan for issues and once again let it create a backup. Select all found issues and Select "fix selected issues". Let me know if it helps you, there are more things to try.
