Early this evening I was on Firefox from 8:00pm EDT at 8:16 Firefox said it had an urgent update when I looked to see if the update was from Mozilla it wasn't so I canceled the update shortly there after by Norton 360 came up with this (Trojan.Kotver!gm2) I restarted my computer and Norton got rid of it. Here is why I'm posting twice this past week I had the same problem from Firefox same virus all three times and all three times the updates weren't from Mozilla!
