browser problems

hi i've had a problem where my browser (google & firefox) wouldn't connect to any site. only browser i can use is internet explorer. i've uninstalled my anti-virus finding out that it's the root of the problem. i've re-installed it and it's doing the same. problem is i can't seem to find where i can change the setting so my anti-virus will let me use the browsers. help? thanks for taking the time to read. sorry if it was worded poorly.

What anti-virus are you using? Have you tried Microsoft Security Essentials? It's all I use on my computers and any I work on.

defender pro. and no actually i've never heard of it
