Description: This is now the most common type of virus. It spreads as an attachment to an e-mail sent from the infected computer. It is also able to spread by other methods - copying itself to shared network disks in local network, sending via IRC or as a file with some alluring name within a folder on a "peer-to-peer" file sharing system.
%SYSDIR%\msvgr.exe
Recommendation: Definitely not required - typically viruses, spyware, adware and "resource hogs"
