internet issues

Win 7 pro laptop.  I can open up the internet with IE and it works fine but I cannot with Firefox.  When I enter an address it just blinks for a bit and does nothing.  Also all my spyware (malware bytes, spybot) and antivirus software (AVG) will not update.  Says it cannot get to the update server.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
