Hello, While this is a good timely reminder, this is nothing new and only addresses a small point of the overall problem. One should always scan ALL files. This is more because of Microsoft Word documents (Excel, etc. too) which can have ANY extension and automagically spawn Word instead of prompting you with a 'open this with?' dialog. (The technical fine detail is this is the case if the extension is not already associated with some other program). ...Eric At 06:08 PM 3/7/2000 +0100, Bram Kerkhof wrote: >-----BEGIN PGP SIGNED MESSAGE----- >Hash: SHA1 > > >SYNOPSIS >The default NAI/McAfee Viruscan Engine configuration does not include >.VBS in the list of program file extensions, thereby skipping .VBS >files when scanning.
