All in all, formatting would remove most virus infections.
If you remove the main infector (being those 2 files) it causes the other services which are infected to stop working (no doubt cause the infector loads its own library which the other services need). So it causes a 1 min shutdown.
So yeah reinstall of Windows is needed in this case, thats until AVs catch up.
The shutdown can be averted with a "shutdown -a" command though. It ignores crashes at the cost of whatever functionality will be lost.
They don't after its aftermath >.<
