I have a Dell Vostro Laptop with the OS Windows XP SP3 Home Editon which recently got infected by trojan vundo virus, and since then it has ceased to start in the normal start up mode and always throws a blue screen.
Its a bit strange that my system got infected even though I had a valid Norton Antivirus.
What I have done till now?
I have gone ahead and run Marlwarebytes scan on my system in safe mode and it did comeup showing around 40 infection, many of which it was able to quarantine, but for few it said it required a system restart, but unfortunately even afer the restart it was not able to remove them completely and all my subsequent Marlwarebytes scan happen to show the same infections again and again.
While searching the net, i happen to come across combofix and followed all the instructions listed in the link http://www.bleepingcomputer.com/combofix/how-to-use-combofix
and my marlwarebytes scan after the combofix run did not find any infections. But my computer still is not able to startup in normal mode and its still crashing with the blue screen.
When i looked into the Windows Event Viewer I see number of errors with event id as listed below
Event ID 7026 - The following boot-start or system-start driver(S) failed to load:
Event ID 7001
Any help in this regards will be really appreciated. I am also attaching the combofix logs for reference.
