How do computer repair shops clean a computer from virus?

Hello, It may be a silly question, I just was wondering how do they get rid of a virus in the computers they clean, I know I use an antivirus program and scan my Pc, and if it finds something, the program will tell me what I wan to do with it, of course I choose delete. Is this the same process a computer repair shop uses?

It is a process both viruses and spyware
