I uninstalled BitDefender Internet Security 2010 last night, in favour for Microsoft Security Essentials. I used Revo to do this. The funny thing is though, the bdagent still runs in the background as per usual, and the all the program files and folders are still there, but I can't delete them. I can't change permissions either because "access is denied."
I can't use BitDefender's remove/repair function either because it doesn't recognise it as an installed program, and I can't reinstall the program for some reason either.
