To delete a file/folder windows will not delete because it is in use, First right click the file/folder, go to Properties, then UNCHECK the box that says "Read Only". Normally you go into safe mode - [ Hold the F8 key after you turn your computer on to get to the Boot menu and select "safe mode"] and then try and delete the file/folder from "safe mode".
IF the file/folder still will not delete then press "Ctrl" + "Alt" + "Delete" and look for the process that could be using the folder/file, right click it and click "end task" - Then try and delete the file/folder.
If the file/folder STILL doesn't want to leave, do the following. Go to Start|Run and type: MSCONFIG
Click the BOOT.ini tab and select "Check all boot paths" if this information says it needs to be changed. Do it.
Then go to "Services" and "Startup" and look for anything loading on your computer that doesn't have any name (Like Microsoft Corporation). DISABLE those!
Restart your computer. Go to safe mode, and delete the file/folder.
ALSO - I strongly recommend you download the trial anti-virus from Kaspersky.com
Kaspersky IS the best anti-virus ever made
Other note: AVP changed it's name to Kaspersky many years ago and Kaspersky is now the ultimate of the two.
Those are the main ways to delete a corrupt file. I scanned this and it seems to be correct.. I am rushing being as I am in school.
I hope this helps
