I have googled and binged it but all I get are suggestions to uninstall and do a fresh install....I cannot do that either! When I try to unstall from the add/remove programs, nothing happens. I've also tried deleting it from windows explorer but it does not allow me to do that either. Not sure what to do?

You can do a disk check with the chkdsk.exe program.

If you run the chkdsk.exe program from a cmd.exe Command window then you can read the response from the chkdsk.exe program.

Open a cmd.exe window:
Start > Run: cmd.exe <press Enter>

At the command prompt (>) type or Copy&Paste: chkdsk.exe /f /r <press Enter> (put a space before /f and /r)

If you get something like: Would you like to schedule this volume to be checked the next time the system restarts? y/n then answer the question with "Y" and close all programs and reboot the computer.

Do a malware check with a few malware scan programs.
You need to use all programs because each detects different malware.
Make sure that you update each program to get the latest version of the database before doing a scan.
