There is a removal tool by Symantec:
URL:
http://securityresponse.symantec.com/avcenter/ven....removal.tool.html
Download:
http://securityresponse.symantec.com/avcenter/FxBropia.exe
It says it removes
"W32.Bropia, W32.Bropia.J and W32.Bropia.N".... That suggests there are more versions which won't be detected by this removal tool, but I'm sure about that...
