Why does this "SYSPROTECT" file or program keep showing up on my computer?

I don't know how to get rid of this. A while back I was looking to get a antivirus program for my computer. I stumbled on the website for sysprotect and I done there free scan. Ever since then it keeps asking me if I want to install sysprotect to scan my computer. If you check cancel then it automatically opens there web page. If you just try to close the site it does the same thing and automatically opens there web site. Also, I dont even have to do anything and there website just comes up and when you try to close it then it opens another window askin you to scan or download something. I just want whatever this is off my computer.I may have put this on my computer by accident. Im not real computer literate so please give me some good detail on what to do please.
