Please Help

Hi. This is my first time posting in this forum. I have recently encountered afew adwares on my office and personal pc. I have done many things and i ended up with my pc being faster again but with an server execution error. Whenever i startup my computer, installservices64 would give me server execution error. Another thing is that when i right click and choose Personalize or Screen resolution, the server execution error would show up again. Lastly, when i press the start button and go to PC settings, it would hang and crash eventually. I am guessing there is a missing registry or some settings behind deleted by the virus. PLEASE HELP!
