If Windows 7, it's no longer called add/remove but "Programs and Features". It's fairly straightforward. Did you also check under Start/Programs to see if uninstall shortcuts are provided for the various programs themselves? As for AV software, is it Norton? You can get free removal tools from Symantec's web site for that purpose.

There are no options like add/remove programs on control panel?
