My laptop is an Hp Paviliondv6233se and just recently i received a computer virus it is called (MS) antivirus. I tried to get rid of it by deleting some files in my windows registry but i gave up, then i downloaded malware bytes, and it deleted some files, but the little icons on the toolbar are still there. Now when i start my computer, the background is black and the only icon that now shows is the recycle bin. Can someone tell me how to reboot my computer to its original, so its like a just got it. Is there a way to do it without the CD or using system restore points because my laptop didn't have any system restore points. Like maybe theres a way to restore it in safe mode? Help would be really appreciated.
