windows-firewall

I have a few computers connected to the internet via a router. I have been having some trouble with this one Windows 7 desktop. I can browse most of the sites without any trouble but some sites where the sign in page switches to a secure connection (https), the page does not load. It's not all of the sites though. I'm able to sign into gmail and a few other services that I know use https . The sites I'm having trouble with; yahoo's sign in page and the one that I have been using to test across different systems, http://iforgot.apple.com (which switchs to https) ;this particular site, i can access from other computers on the network and my phone.

I only have windows firewall running and AVG. I even tried to stopping windows firewall but it did not help.

Everything was fine last week. All I have installed in the past week is VOIP softwares namely skype, ooVoo and windows live messenger. I'm not sure how to find out what's being blocked and why and how to unblock it? Any suggestions would be greatly appreciated.
