At least that is what I think is happening. Everything was fine, and then I got a notice last night that there was an upgrade available for Zonealarm. So, I installed it.

This is what version it is:

ZoneAlarm Pro version: 10.0.250.000
vsmon version: 10.0.250.000
Driver version: 10.0.250.000
ZoneAlarm Browser Security: 1.5.322.0
ZoneAlarm ForceField Spyware Scanner: 1.5.322.0
ZoneAlarm ForceField Anti-Phishing Database: 1.2.104.0
ZoneAlarm ForceField Spyware Sites Database: 04.155

This morning, the computer hung and would not shut down. I did a manual turnoff.

This afternoon, in the space of two hours, I have had two blue screen shutdowns, which MicroSoft advises is due to firewall/anti virus programs. I'm thinking to reinstall the older version of Zonealarm - which was working fine with my Nortons. Should I do that, or is there another solution?

Thanks for any help!
