Re: Norton antivirus won't delete adware
Frequently, spyware/adware/trojans are being "used" and "locked" when in "normal" Windows. As a result they can't be removed at that time. Try restarting the computer into "Safe Mode", then running Norton, or and other spyware removal tool. It should be able to delete the file while in "Safe Mode". If not, try removing the file manually.

Hope this helps.
