My laptop got infected by rootkit virus. The laptop functions normally for 5 or 10 minutes and then gets hanged where in you will forced to witch off and switch on. Then a blue screen appears and this is what it says "DRIVER_IRQL_NOT_LESS_OR_EQUAL". Then i ran the Combo Fix and i had attached the log file from Combo Fix. Please analyze the log file and let me know the fix at the earliest as i am not able to use my laptop.
