jyhppvu probabile trojan

[nikko]

Salve a tutti. Ho un problema..
praticamente in esecuzione automatica ho uno strano file chiamato jyhppvu che probabilmente è un trojan dato che virit me lo segnala come tale ma non riesce ad eliminarlo..ora sto facendo una scansione con avast ma dubito che riesca a risolvere il problema..
Sapete come aiutarmi?
Grazie
