ciao a tutti, come ho gia visto molti hanno avuto il mio stesso problema…il mio avast ogni volta che collego il pc ad internet mi fa apparire 10/16 notifiche di infezione bloccata per URL:Mal e il file infetto in questione sarebbe appunto il file svchost.exe situato nella cartella system32 potete aiutarmi cosa devo fare? ho provato i vari malwarebytes, ccleaner ma nulla continuano a venire fuori le notifiche ogni volta che attacco la chiavetta wifi 
qui ci sono i log di FRST devo mettere anche quello di aswMBR??
Per adesso va bene cosi,
ho chiesto ad un malware removal specialist di controllare i tuoi log, spero ti risponda entro sera
ciao
