I am attaching here the Combofix log generated. My Windows Vista has been attacked with a virus infection, possibly a rootkit as detected by my antivirus.
I am unable to connect to internet for more than 2 minutes, as the system shuts down. I have found a bndvywaq.sys in sytem32/drivers folder, which seems to be cause. But unable to delete it. I have used Combofix & MS security essentials, but none have been able to solve this problem or delete the rogue file.
I would be soon attaching DDS and Gmer logs, but please have a look at this log if it helps.
Kindly suggest some actions so as to remove this infection from my system as I cant access my machine for Internet. Thanks a lot for help!
