Certain web pages blocked!
	
	
		Hello there! I'm totally at a loss!
I installed kaspersky, and a warning came up that warned me of an intruder. I clicked the button to block it, and then I started thinking that perhaps it was actually asking me if I wanted to block Firefox.
Ever since then, I've had a big problem with Firefox and internet explorer! Some pages will open, including my email and this forum, but anything I type into the address bar or try to access via Google or other search engines just goes into loading mode forever. The pages never go through!
I tried removing kaspersky through "add or remove programs," but it said that I wasn't authorized to remove it. I tried removing it manually, which looked like it was working, but if I go back to "add or remove programs" it's still there. When I try to remove it now, a message shows up saying that a program has to be installed for it to be removed. 
I tried installing a new version of avast, and it looks like it went through just fine. It found infection (trojan-gen), and I deleted the files, but the web problem is still there. :(
I have tried fully clearing out what I could through spybot and I have run a "standard" scan from avast in safe mode. I even removed Firefox and installed the new version of Firefox from scratch. Still, I can't access those web pages.
One of the times I went into safe mode, I was actually able to use Google. I thought the problem was solved, but as soon as I went back into normal mode, I found myself at square one.
I'm so desperate to resolve this problem. Please, please, please help me to figure out what to do. Also, if there is any way to solve it without having to access the internet from another computer, it would be *much* preferred. Can I? Thank you for your help!
