I have had the same problem as well on two different machines the name was different on both machines , however it did start with “Update For” and had the same icon - this appears to be the last thing i installed on each computer,Machine 1 was “Update for Image Pack” on machine 2 it was “Update for Codec Pack”
Just a little food for thought
could it possibly have been installed by a Toolbar? as on both machines i had downloaded something that installed the Delta toolbar automatically
has anyone else had the same thing happen without Delta toolbar?
