[MLUG] New viruses using encrypted zip

["Russell Horn" <EMAIL:PROTECTED>]

Just wondering what folk are doing about this week's spate of new viruses,
several of which are hiding themselves inside encrypted zip files.

We have anti virus software on the desktops as well as the mailserver, but
we have new variants every few hours it seems so there's a constant battle
to keep definitions up to date before a user opens one of these files.

For those that haven't seen them, they come through in a message like this:


Subject: Notify about your e-mail account utilization.

Dear  user of mlug.com,

We  warn you  about some attacks on your e-mail account. Your  computer may
contain viruses,  in  order to  keep your computer and e-mail  account safe,
please,  follow the instructions.

Pay attention  on attached file.

In order to  read the  attach  you have to use the following  password:
33252.

Have a good day,
     The mlug.com team                               http://www.mlug.com


Now that's not going to fool many folk here, but if they improved their
language we could have a real problem. Remember we saw this last year

If one of these viruses looked that authentic and came with an infected
attachment that we can't scan at the gateway...

Russell.
