Webbrowser Not Opening, Mozilla, IE , Opera?

I haan issue before about product key got it solved, but didnt do the laptop clean. I know maybe thats why im having so many problems now, but I have no ack up right now and it was my fault for resetting the laptop back to a restore point back in ocotber when it wasnt working. For those who dont know , I told it to a repair center, they wiped it and installed a trialversion of windows 7 I managed to get my product key now, so Im really not sure why I have all these viruses pop up msgs, Ive been using all the reccomended security protections.Iwould like to- I cant open any web browsers at all, Im typing this msg from realplayer. But even when I type in an address bar I cant access theinternet through there either, for some reason only through real player.

Mozilla wont open at all, opera tries to open a msg manges to pop saying 'opera in not default browser' etc, but goes after litrelly 2 seconds. I just tried openening IE it opnened, then froze , than crashed now it wont open at all.Opera wont let me delete it, my broiwesers were working fine since I dl opera its been maybe 1-2 weeks since than so how can it be that. Problem 2-Right now its very difficult to type this messege, no matter where I type on my laptop, internet, wordpad, MS Word etc the lines get all mixed up. Say I typed 3 sentences, the last sentence Im writing will go to the top or a few words will for some reason go in the middle of the paragraah or the beggining without me doing anything!Ive been having problems with my laptop for a while now. Usually the errors not being able to open anything on my desktop, so what I do is I take out the battery leave it for a while and it usually works. Ive ussed CCleanup, Malwarebytes, and avast
