If you don’t disable system restore and something is detected from the system folders then system restore saves a copy in the system volume restore _restore point.

It isn’t much of a problem there, but if you use system restore some time in the future you could be reinfecting your system. Even then as has been said in the past a file without a run command, etc. it not active, so it shouldn’t present the same level of risk/potential. But it is better out of your system than sitting dormant waiting to be detected.
