Hi njasm, welcome to PCSF.
First thing I'm going to ask is, if you've downloaded McAffee Suite from the internet? If so, it could be that what you've downloaded, which most probably had a crack, it was a virus or sometype of other malware. If you just got it from a shop, this is not the problem.
Second thing. I'm going to refer to a very recent thread by Alan.
http://www.pcsupportforums.com/compu...-firewall.html
In the thread, Alan shared with us a detailed review comparing different firewalls. If you search for McAffee Suite you will find that it is rated as very poor. SO my suggestion would be to get rid of it and get something else. If you need help of what to get we will help you find something for you.
Next, in your original post, you said that it is directing you to porn. For sure, even if it's rated as Very Poor, a Security software such as McAffee is not going to direct you to porn. So the problem is eighter the one mentioned earlier or could be that you have malware (spyware, adware, virus) installed on your hard drive.
Do you have any anti-spyware, anti-virus or other firewall software other than McAffee? If so please state what you're using. First thing I would do is download these software (all free):
Lavasoft Ad-Aware free edition (anti-spyware)
Spybot Search & Destroy (anti-spyware)
AVG free edition (anti-virus)
... update them, and do a deep / full scan of the system. Remove any malware detected and get back to us with the results. I'd suggest you do a second scan as well just to make sure.
I will stop here for now, so you will not get confused

Your problem is very popular so don't worry. My opinion is to backup your important data frequently just in case something happens.
