VBS/Happy

This virus is a true parasitic infector. It appends itself to then end of any script files in either ; · The same folder as the virus · The root directory · Windows\Desktop · Windows\Start Menu\Programs\Startup · Windows\My Documents

It also creates a copy of itself in the Windows folder called avm.vbs and inserts an entry in the registry so that this is run automatically at startup. This virus has no payload, is easily repairable, but could be quite dangerous due to it's installing itself into the registry. It is dropped by the W97M/ColdApe virus.
