I currently use Norton Internet Security and Norton AntiVirus (both are
the 2003 versions) under Windows XP Pro SP-1 on my home computer. They
are pigs for memory. Task Manager currently shows (I only booted about
10 minutes ago) the following memory usage:

ccApp.exe = 14,356 KB
ccEvtMgr.exe = 3,980 KB
ccPxySvc.exe = 118,944 KB
Navapsvc.exe = 996 KB
NISum.exe = 5,800 KB

That's a whopping 144 MB. The SymEvent service uses svchost.exe and
there always multiple instances of this process so I cannot tell which
one has SymEvent rolled into it, so the actually memory consumption is 2
to 17 MB more than 144 MB.

For users of OTHER products (i.e., not Symantec) that have BOTH an
anti-virus and firewall running, what is the impact on your memory usage
for those products (and please name your products)?

Thanks.

Something looks wrong there with that ccPxySvc.exe..

I use Sygate 5.5 and Avast AV. Right now, they're using:

Sygate = 11,420 KB
Avast = approx 14 megs total.

I used to use NAV, but it stopped working after I uninstalled and
reinstalled it several times. The updates reverted to some crazy date
like Aug 2003 and I still have several months left on my subscription.
Beats me what happened there, but I got fed up with Symantec and
installed Avast instead, which seems to work very well, and it's free as
well. Doesn't use any CPU resources to speak of.

I'm also very happy now with Sygate.

Kerio Winroute 2.1.4 uses 12mb; although, I dont use that anymore, I spent £35 on a small form
factor Pentium 2 which is now my iptables firewall for the network, running debian.

F-Prot AntiVirus uses 2mb; and has fast heuristic scanning of executables, fastest ive used so far
for on-the-fly scanning of run programs. Only thing F-Prot lacks is features, but being simplistic
is good, as you can see NAV has lots of features, many of which I would never uses and has a massive
memory/processor footprint.

So altogethor, 14mb when using software applications.

That's Symantec transparent proxy. Remember when, for example, Norton
Antivirus used to change the e-mail account settings to insert its
proxy? It modified the e-mail client's account so the server specified
pointed at its proxy and added the original target mail server to the
username field (which is how, for example, SpamPal, YahooPOPs, and other
non-transparent proxies still work). Symantec now uses ccApp (Common
Client Application) and the ccPxySvc (Common Client Proxy Service) to
channel all their protected data streams. It is also a common point of
failure. If ccApp, for example, because partially brain dead then you
lose web surfing but can continue using e-mail, or visa versa, and if it
goes completely dead then you lose all connections. I came up with a
batch file to kill ccApp and stop and restart the Symantec services and
sometimes it will get the dead product working again but not always and
so sometimes I still have to reboot to get them to load in the correct
order. This isn't an isolated problem to just one computer or one user.
Most users only know that something went wrong with their networking and
do a reboot to get it working again. ccPxySvc is used by both NIS and
NAV. NAV even adds a BHO (browser helper object) to monitor data
streams through IE, so that also adds to the memory footprint when you
are browsing.

Although using a transparent proxy makes its use easy for customers and
ensure that their data passes through it. It also makes it impossible
to configure your clients to bypass the protection and disabling it
doesn't always get it out of the way enough to eliminate it completely
from interferring with the traffic (if ccApp goes dead then disabling
NIS does nothing to rectify the problem; you might open the valve all
the way but the water still has to go through that valve, and if it is
blocked then you won't get much water no matter how open is the valve).

If you look at your NT services (run services.msc), you'll find the
following are listed for NIS and NAV:

Norton Antivirus Auto Protect Service (navapsvc.exe)
Norton Internet Security Accounts Manager (nisum.exe)
ScriptBlocking Service (sbserv.exe)
Symantec Event Manager (ccEvtMgr.exe)
Symantec Network Drivers Service (SNDsrvc.exe)
Symantec Password Validation Service (ccPwdSvc.exe)
Symantec Proxy Service (ccPxySvc.exe)

Not all of these remain running but several will load on Windows
startup. For example, on Windows startup and before you login, one of
them will run to validate the hashing of the registry keys (they aren't
in plain text anymore) to check if something has attempted to tamper
with their definitions to disable the product.

So, what firewall and anti-virus products do you run? And what is the
memory impact for those programs?

Kerio Personal Firewall v4 - Less than 16 megs
Norton AV 2002 - Less than 11 megs
I have several svchosts, totalling less than 18 megs, but they may not
have anything to do with either program though.
