falsi allarmi oppure devo preoccuparmi?

[mauri_bs]

Antivir mi ha appena segnalato un "droper" dr.who in c:\system volume information\...\1242i1ecc
Quindi in un area da me nemmeno accedibili
Ma che sarebbe un droper? elimina file forse ?

Ho fatto partire il pc in modalità provvisoria e poi ho fatto 1 scansione completa con VIR.IT ma niente ...

Ecco invece 1 log di hijackthis:

AGGIUNGO a 1 certo punto e prima della segnalazione di virus di Antivir, zone allarm mi ha segnalato l'accesso + volte a internet di 1 un ottimizer per il framework .NET ... e io ho consentito pensado a qualcosa legato all'upgrade di Windows tra l'altro del framework .NET ...
