I want to remove DivX Setup from my computer. A few days ago I had a DivX update and a whole bunch of additional stuff got downloaded with it causing my pc to act up big time ever since. I tried deleting DivX Setup from the control panel but it doesn't work. First I got the uninstall bar that didn't progress; now even that doesn't show.

This is the message I get when I try to delete ANY of these files:

Cannot Delete DivXUpdate.exe: Access is denied.
Make sure the disk is not full or write-protected and that the file is not currently in use.

I also tried uninstalling it in safe mode but after going back to normal mode DivX setup is still showing on the control panel program list.

How do I get rid of this darn thing???
