virus maledetto

[gepyilfolle]

ciao a tutti
da un paio di giorni bit defender mi blocca un virus che si trova in:
C:\windows\system32\svchost(memory dump)e loclassifica come un behaveslike:win32.irc-backdoor.
però non riesce ad eliminarlo, dato che bit defender non si avvia in modalità provvisoria posso eliminarli a manina???

Ma il nome del file infetto è proprio questo? C:\windows\system32\svchost(memory dump)

Il log di hijackthis è pulito.
