Windows Release Delay

Somehow my windows machine got infected with spyware / virus. I am
concerned that even if i clean my machine I may not be free of the
spyware / virus and i’m curious if you guys want to advise me. Do you
think if I install symantec and get it cleaned then would my release be
clean enough? Or do you think i should wipe the drive and reinstall

This is why i dislike windows.
