My computer has been infected with Win32:Vitro worm. I had tried to solve the problem of Win32:Vitro by using Avast Anti Virus and Malwarebyte Antimalware tools. The tools had asked me to restart the computer. When i restarted the computer, i could not log in anymore. Now every time i log in, the computer automatically logs me out the very next moment automatically. I am posting this from another computer. What can i do now to solve the problem ? Any help is greatly appreciated.
