Need Help! I have this computer from last 3 years but never faced any problem with the anti virus system. Currently i am using the avast anti virus to detect the viruses from my computer. But i do not know what is happening to avast as it gets disabled everytime. How does it happens and i want to remove Win32.Worm.Koobface.ALX which i have got at the time it was entering but now my spyware does not help me to remove it.
