BrOwnIcOle wAndeRiNg Up thE clOuD

I am totally ruining my laptop...
It was infected so much virus, like 800 of them, which system cannot recover or fix it, I cannot make any backup files for all my documents and my precious photos since I took last Octorber, everything is going to disappear by that god damn virus...

I was sitting at home all afternoon, staring at my laptop, and trying to delete some of the big files that maybe helpful for the system to run some protecting software... but it was failed. And all the documents was running (opening and closing) like a turtle, so slow that I can't even know were they gonna followed by what I tried to do or not... that sucks

what the hell can I do now, can somebody tell me??
