McAfee Enterprise 8.5.0i virusscanner gaf onderstaand als resultaat van een scan:

NTOSKRNL-HOOK (gedetecteerd als 'Generic Rootkit.d!rootkit)
NTOSKRNL-HOOK (gedetecteerd als 'Generic Rootkit.d!rootkit)

c:\windows\system32\drivers\gaopdxyishscjf.sys (gedetecteerd als DNSChanger.gen)
en nog enkele bestanden gedetecteerd als 'Generic FakeAlert.h'

Weet iemand of dit kwaad kan en zo ja, wat ik dan kan doen?

Ik heb een computer met een Core2 Quad Q9300 processor en met Windows Vista ultimate. Ik heb de laatste tijd vaak last dat ik een 'normale' website niet kan laden. Ook kan ik geen updates meer binnenhalen via de Microsoft site. Ik krijg steeds een foutmelding. Als ik handmatig Microsoft updates wil ophalen wordt foutcode 80244019 gegenereerd. Ook updates voor Windows Defender kunnen niet meer worden opgehaald.

Wie kan mij helpen om dit weer in orde te maken?
Vast bedankt.

Het beste is om even een Hijackthis-logje te maken en te plaatsen.
