I have just purchased this antivirus protection from Mcafee and can't get it to run beause I keep getting a message from Security Shield which I think is another virus protection service. I tried to uninstall it but didn't see it on "my computer" or the uninstall programs. I have windows xp. How can I get Mcafee installed and running. Also I keep getting porn sites coming up, how can I stop that.

There is an excellent removal guide here: http://www.bleepingcomputer.com/virus-removal/remove-my-security-shield
Scroll down the page as the first links you see are all advertising.
These fake anti-malware things get past most antivirus applications unfortunately.
I trust that your machine is XP SP3 and fully updated?
