need some serious help

[MIZantine Empire]

ok i will add some screen caps of other probs i am having. i will try to explain the ones i cant take screen caps of. one, i cant send any emails. it tells me javascript error, and 95 percent of the time closes the browser, and everything else opened. i take online college courses, and those i can not access anymore. i can log in, click into my classes, but i cant open any assignments (this all started happening maybe 3 days ago.) i have ran about 5 virus/spyware scans, and even recovered my comp to a previous time. (i have a shit ton of files, and i dont wanna lose them by doing a full recovery) problem 3, when i do a search on google, yahoo or any search engine (for example if i google nfl.com, or something like that) the links that come up in the results are the right links. when i click them they become some 3rd party search site with different links (im assuming virus related) no to some screen cap problems so u can maybe see what i am talkin about. ok well i couldnt screen cap the other probs but i will try to explain. every different website i browse usually gives me a pop up box. two different kinds i have seen so far. one is two seperate white boxes that i have to click close, and the other is a small square box that has 3 links in it that i have to close as well. 90 percent of the time when i close them a different window pops up with what i can imagine is bad stuff (like i said this stuff has only been going on for about 3 days.) please help. any questions i can try and explain more clear. thanks in advance guys. oh that screen cap is of when i click on my email. it pops up my inbox with that website attached. i know it isnt good..lol
