SVCHOST hangs server until process is killed


i have windows 2003 server r2 standard edition, service pack 2 has begun "hanging".

server specs
hp proliant ml370 g5
dual intel xeon e5320 (8 cores)
4gb ram
windows 2003 r2, service pack 2
terminal server
sunbelt software vipre enterprise antivirus software


during normal operation, users start disconnected server , unable reconnect. console become unresponsive , ther server has hard rebooted.

have found svchost process ram usage starts grow rapidly , "hangs" server.  if kill process server recovers , performs thing starts over.

svchost has following services registered:

application experience lookup service
com+ event system
, support
server
workstation network location awareness (nla)
rasman
schedule
sens
windows management instrumentation
computer browser
net logon
file replication service

svchost starts out @ boot-up using 18mb ram, after 45 minutes using 45mb ram, @ little on hour using 85mb, 90 minutes using 135mb , 2 hours using 225mb+ (at 5am morning after being booted 15 hours using 625mb)

long kill process before hit 100mb of ram usage, of services start correctly.  however, once process exceeds 100mb of ram, server service failed start access denied error, once happens forced reboot server because there no shares.

when system hangs, doesn't log errors in event log relate cause.  it log errors related symptoms of crash (winlogon errors, etc).

4 weeks ago, had issue server spontaneously rebooting.  it turned out faulty broadcom nic drivers. replaced drivers , reboots stopped. (i bring additonal information)

also, has employee load fake sysinternals antivirus software on "her computer". has thin client ... our a/v caught , cleaned it.  subsequent scans of server have been clean, can't wondering if may related issue experiencing now.

suggestions appreciated.
