I am trying to uninstall PC-Cillin Internet Security but when I do it asks me for a password and I have no idea what it is and I don't even remember ever putting one in, how the hell can I bypass this as I really need to uninstall so I can install a different virus scanner
Have you tried simply disabling it? If that works you can forget about it and install another antivirus. It won't matter if it's still on your computer if it's not functioning. I use AVG antivirus which is free from www.grisoft.com and it's been good over a year or so!. Hope you're successful!
