Need help with Virus DSV.exe. can't restore, launch browser or anything?

so i got some bug that keeps making my system try and install some anti virus software and pops up all the time. I've tried to get rid of it using AVG and others but its always been there. Yesterday I noticed that there were many programs running on my task manager that shouldn't be and that I didn't recognize. I closed them, one of them kept coming back called DSV.exe every time i tried to do anything. I've tried different ways of restoring, but i don't have the original windows disk. I managed to get AVG to run at some point. it removed a few things, but didn't fix the issue.

Now I can't boot up with out this taking over my computer and not allowing me to launch or load any programs. any ideas?
