How is IE interfering with your antivirus? What antivirus are you using? You have to use IE for Windows updates, and I imagine there're other dependencies as well, so I really think removing is not a good idea. You could always install Firefox from http://www.mozilla.org or Chrome from http://www.google.com/chrome .
Internet Explorer is conflicting with my Anti-Virus software. If I uninstall IE will that prevent my Windows 7 OS from operating properly?
