New variation to MYDOOM

["Staves, Steve" <SStaves () mail canfor ca>]

Be on the lookout - We just had an infestation of a nasty variation to the
MYDOOM virus - Now dubbed, I believe as mydoom.f.  If randomly overwrites
files and created havoc on all network shares.  So far we have had to delete
in excess of 1500 files from one server that got infected through shares.
We may of had the undubious honour of being the first report on this issue
as Mcafee did not even know about it yesterday.
