I’ve a Vista Ultimate installed on a DELL Latitude D620 laptop. The problem
started a few weeks ago when Symantec Antivirus reported catching Clone War
(1) on my computer. I’ve since done a few clean scans using various scanning
programs but some system files seems to have been lost or are corrupted. I
tried running sfc /scannow under admin cmd window and also after starting
the recovery cmd window, but got the same message both time:

Windows Resource Protection could not perform the requested operation.

Even the automated recovery option to fix boot problem failed. I’m able to
boot up the windows and its generally funtinal but quite a few things are not
working e.g. I can’t open the personalize window from the desktop right click
menu.

Unitl late last week I was able to run the sfc and it reported a whole bunch
of problems but did not automatically fix anything. I didn't have time to
look into manually fixing things but now even that's not working.

Please help!
