I wouldn't use it until you get someone to help you follow the procedure I described or you totally lose all your data and stuff and reformat your system and start fresh.
I've already told you what you need to do, if you don't do it or if you don't have anybody that can help you then you will have to lose all your data and do a fresh install of windows. You are so badly infected that nothing will run unless you do the procedure I told you to do. I suggest you take it in to a computer shop and have them either clean the infection or get your data backed up for you.
Depends on how much they charge where you are at. Do you have any friends that are computer savvy that can do the procedure I told you to do?
