Podejrzenie wirusa - komunikat w NOD32

Dla specjalistów Bezpieczeństwo
#1 
File C:\WINDOWS\system32\drvxok.dll is infected with application Win32/Hoax.Renos.NAH. The file can be deleted. It is strongly recommended that you back up any crucial data before you proceed.

Przy skanowaniu NOD32 pokazał coś takiego. Czy mam usunąć ten plik?

#2

Ok, ale w gruncie rzeczy nie odpowiedziałeś na moje pytanie:

Jeśli masz ten plik (w co wątpię) na dysku to go usuń ale prawdopodobnie NOD sam go usunął.
