Allows backdoor access and control
Virus:Win32/Ramnit.F creates a backdoor by connecting to a remote server. Using this backdoor, a remote attacker can instruct an affected computer to download and execute files.
The virus creates a default web browser process (which is invisible to users) and injects code to it. The infection and backdoor functionality occurs in the web browser process context, presumably for the purpose of bypassing a firewall.
