Heads up and get your computer securty updated immediately as the next thing you do today and run a full system scan.
A brand new high-risk threat created less than a week ago is now infecting PC's, laptops and notepads through various websites.
While using my Firefox web browser I was on a popular Bible prophecy website just looking at one of their webpages when a popup occurred when my just updated Norton 360 AntiVirus detected the maleware attempting to enter my machine. It was lightspeed fast! I'll send a note to the site owner privately, obviously the server his site is hosted on has this malmare setting up shop to infect others.
The source file for this high risk executable file is rundll32.exe and the file it will create on another machine - if not stopped in its tracks - is skggx.dll, otherwise known as SONAR.Module!gen3.
Update your antivirus and run a full scan on your machine. This virus appears to be bad juju and is nothing to mess with.
