To clean your infections, I suggest following this post: Start here
Contained within that guide are step by step instructions on tools you can use to fight malware. These programs are tested and have been proven to be a great start in cleaning your computer. Best of all, they are free. If your issues remain, continue and post a HJT log here.
One word about HJT posts... That forum is very busy. It takes time and research to work a single log, so please be patient for a response. Do not bump your topic. We try to resolve logs on a first come/first served basis. By bumping your log you will be pushed back in line due to the new date of your bump.
Good luck stupot1,
