I am using XP SP2 in my comp. Recently my comp got infected and scanned the pc to clear up the thing. Now i need to manually clear the unwanted registry entries. But when i try to delete those entries it show the message access denied or cannot delete. I do not understand what is issue with this thing. As i said that i had scanned the pc and removed the virus, but even after that how come the registry file is still affected. So, what i have to do for this issue.
