Salve a tutti,
è da un pò di giorni che sul mio pc, Avast mi rileva, ogni volta che mi connetto al wifi, svchost con infezione: URL:Mal, ogni volta con un url diverso. Ho provato ad usare Malwarebytes, AdwCleaner e la pulizia browser di Avast, ma nulla. Cosa dovrei fare?
Ciao,
esegui una scansione con farbar e allega i log

Innanzitutto grazie per aver risposto subito, posto qui sotto i log:
Ciao,
ho chiesto ad un malware remover specialist di controllare i logs.
Appena lo farà ti dirà come procedere

If you do need to keep Java then download JavaRa
Run the programme and select Remove Java Runtime. Uninstall all versions of Java present
Once done then run it again and select Update Java runtime > Download and install Latest version
