Thanks for replying. I just checked my Outlook Express e-mail message details and the last time this tag was attached was on August 20, 2005:
X-Antivirus: avast! (VPS 0533-5, 08/20/2005), Inbound message
X-Antivirus-Status: Clean
Three items that could be the problem are:
1) My Avast scanner icon in the bottom part of the screen shows that 3 providers are running (Script Blocking, Network Shield and Standard Shield). Though my Internet Mail shield is active, it's not showing as "running" with the other three and not appearing in the "pause" option, although it does appear in the "stop" option and the run time counter is active.
2) Could it have anything to do with running Zone Alarm's e-mail safe?
Zone Alarm's AV monitoring doesn't detect Avast either.
3) I've also noticed that in the Avast setup that I can't send SMTP alert using the test feature.
I also have MS Anti-Spyware running with its security agents enabled.
