The virus, dubbed W32/Yaha.M by MessageLabs, has seen its numbers explode with over 7,000 being stopped by MessageLabs on Monday. So far more than 17,000 copies of the virus have been detected by MessageLabs, leaping it to the fifth most common virus sent through the system since records began.
In response to the increase in occurrence, Symantec (which has dubbed the worm W32.Yaha.K@mm)has raised the threat from a Category 2 to a Category 3.
The worm arrives in the form of a .exe or .scr attachment to an e-mail with a variety of subjects and messages, and contains it's own e-mail client to mail itself out, forging the from address. It also attempts to close down a number of firewalls and antivirus programs.
"leaping it to" what the ?
