Soft Soldier

HELP! Soft Soldier: It popped up on my firefox browser and was there until I restarted my macbook pro! I googled it. It is a rogue virus pop up, but I need your help. Is this on my computer now, or did I dodge it by restarting?
PLEASE HELP ME!

Make sure you have no apps running. Go to applications>Activity Monitor> CPU (bottom left). If the %User or %System is unusually high even though you are not using any applications, it might be on your Mac. There has yet to be a virus created for the Mac that most people know of. I wouldn't worry about it.

It's not a virus.
It's a trojan that won't cause any harm to your Mac.
Closing the browser will get rid of it.
