Most third-party antiviruses cause more problems than viruses do in my experience. They tend to hook into system calls and slow down the computer in hard to diagnose ways. Sometimes they don't implement the hooks correctly and cause subtle bugs on top of the slowdown. I only use built in ones (such as Windows defender) which at least have the pushback of some other teams that own the APIs that are intercepted and tend to strike a better balance.
