Hi all,

Just an extra note...

Adaware pro uses the feature Ad-watch, wich can be useful. Like Guru
said.

It works like an anti virus agent.. checks constantly...

This way you could setup workstations to run it in the background. You
could even create a package and let it install as a service wich runs in
the background on the system account.. This way normal users won't be
able to kill it...

Spybot also has the added advantage of being able to /immunize
/individual pc's from common threats which can be very useful and would
require no monitoring. I personally find Adaware to be the better
removal tool at the moment due to the number of definition updates it
gets but if run alongside spybots immunization function it is very
effective on my home pc. I believe Adaware Pro does run in the
background of pc's thus negating the need to constantly run it but im
not sure about using it on linux.. Not sure about the other methods as
i'm no expert on such things.

Regards,

Guru

   I run several small networks using a Linux Server to act as a
Firewall/Proxy HTTP/Mail server/Caching DNS/DHCP/Samba File Server for
Windows networks (98/XP/2000).

   I also do desktop maintanance and I'm seening a growing problem in
Spy-wares and malware. It is becaming unmanageable to deal with it.

   I've tryed to educate users, but they really seen not care, they
click
on everything they can.

   So I'm looking for some solutions that can make my life easier, and
I
want some comments on what I've came thru to try to find a balance
between
all solutions that can prevent most infections and keep the usability
of the
system.

   1) Spy-bot : Looks to me that it is the best tool to remove
spyware/malware, but it is host directed. It's hard to run it on all
machines periodically. There's any way to centralize it ? Or there's
any
other program that will run in a centralized way?

   2) Firewall blocking List : I've seen some IP lists that will
prevent
spywares to "call home". It is usefull to detect machines that are
infected
and blocking spyware to call home, but it does not prevent users from
getting dirty. It helps a lot and I'm using
http://www.geocities.com/yosponge/ list. Does anyone knows others
lists?

   3) Content filtering : Viruses spreads by mail, spyware/malware
spreads
mostly by HTTP. Maybe filtering some words/parterns in HTTP Proxy I
could
block some problems.  Dans-Gaurdian seens to be a solution for this.
Does
any one knows any list of words/sites, file extensions or any
alternative to
this?

   4) Removing user access to his own machine : Removing users
privilegies
(at least in XP/20000) will make spyware/malware infection harder or
not?
Looks to me that at least IE infections still contiunes. At opinion on
that?

   5) IDS : Using snort or any other IDS will help me with
malware/spyware
detection?

   Is that all I can do? I'm open to any tip, solution or reading that
can
help me with this annoing problem.


Regards and thanks in advanced for all replys,
Thiago Madeira de Lima.
