Vista - Certain pages don't load while others do

Okay, I'll be completely honest here. I have little to no knowledge of computers, but I happen to really like having mine functional. It's been messing up for a few weeks ever since I made a really stupid decision about downloading something I shouldn't have. We worked on it for about three hours last night, and finally got three Trojans and a tracking cookie off... And everything is great, except for one thing.

There's certain pages - MySpace, Gmail (I had to get on my mom's computer to activate my account for this site), etc, that just WON'T LOAD. They'll load for two minutes or six hours, and the screen is the same - the white screen that usually only shows up for about three seconds. I've gotten my stepdad to look at it, and he helped to get it working again, other than the sites that stubbornly refuse to load. I asked for help on a tech support forum on LiveJournal, and that didn't really help.

So I'm hoping someone here can XD Seriously. If you can help me with this, I'll worship the ground you walk on or something.

Edit: I'm also sure that it's not the connection. My mom's computer works just fine, loading every single page she wants to look at. So does my dad's, on the completely separate network from my mom's. It's mine that's being stupid.

Hello A_Pathetic, and welcome to Vista Forums.

You may have a bad IE7 add-on that is causing this. This tutorial will help show you how to check for this and fix it if it is.

Internet Explorer - Reset

Hope this helps,
Shawn

I use Firefox though :\ I don't ever use IE unless I need to.

Oh, ok. I'm afraid that I do not know what to try with Firefox though other than checking through the add-ons for it to by temporarily disabling them one at a time.
