At the AVG free forum:
This vdb update has been released today, AVI 268.18.8/718 - Added detection of new variant of Worm/VB, Worm/Agobot.
AVG Free has found this worm.
How dangerous is this?
It was found in a program called,
Firefox Setup 188.8.131.52.exe
It did NOT find this on March 9, 2007 or before this date.
Found it on March 10, 2007.
It was the install program. I put it on a disk a while back and forgot to update it. I don't feel it's a threat, since it's a Mozilla Firefox file, unless it somehow got infected.
