è un po' difficile pretendere che venga rimosso da un antivirus che non c'è in esecuzione

ad ogni modo sei infetto da disk knight.exe che ormai èmolto vecchiotto come virus quindi segui le indicazioni della guida apposita e prosegui li:
Disinfettare da disk knight.exe

dopo dovrai disinfettare anche le chiavette usb e hd esterni

chiudo questo thread essendo doppione
