For users of Norton AntiVirus *but* which have NO other Symantec
products installed, how much memory is consumed by all processes
associated with Norton AntiVirus?
I have Norton Internet Security 2003 which includes an integrated Norton
AntiVirus 2003. Together their memory footprint is 134MB. Uffda, what
a pig! After struggling with their firewall for a couple years on
several machines, wasting lots of time with their tech support, and
having to reinstall numerous times, I'm dumping their firewall.
However, I still like their anti-virus product. However, after trying
to install it separately, and after talking to Symantec, I find that
Norton Antivirus cannot be installed alone. For NIS2003, you can
install just NIS2003 or NIS2003 + NAV2003, but you cannot install just
NAV2003. As a result, I am evaluating what other anti-virus software I
may use. I'm not really interested in users' opinions as to what they
think works best because no user gets full exposure to all in the wild
viruses. After reading several independent lab tests on many anti-virus
products, the only ones that get high ratings (over 98%) are those that
use the KAV engine, which is Kaspersky (and, I think, NOD32).
In any case, if and only if I decide to continue with Norton AntiVirus,
I'd like to know what just what is its memory footprint. I can't
install it separately from Norton Internet Security. If you have more
than one Symantec product installed, they share some processes and add
others so it would be difficult to isolate just the memory usage for
Norton AntiVirus alone. The auto-protect service (navapsvc.exe) is
small at just 996 KB. If NAV uses the ccApp.exe (Common Client
Application) process, that increases the footprint. The other processes
I remember were ccEvtMgr (Symantec's Event Manager) and ccPxySvc (their
transparent proxy). If ccPxySvc is NOT used for NAV then the memory
footprint for NAV would go way down. All the NIS + NAV processes ate up
134 MB of which somewhere around 115 MB of that was just for the
ccPxySvc service. It NAV does not use that piggish proxy process then
maybe it would only consume 19 MB. However, although NAV might not need
the transparent proxy for web browsing (since they install a browser
helper object to IE), they might still need it to handle e-mail data
streams. ccPxySvc was the pig so if it isn't used for NAV alone then
the memory requirement goes way down.
