I ve had success combining Kaspersky AntiVirus 7.0.0 (today at 22.214.171.124) and ZoneAlarm Pro 7.0.408 under WIN XP SP2 Home since August of this year using the Kaspersky First strategy recommended by Kaspersky Forum.
I am now researching
the upgrade of ZAP from 7.0.408 to 7.0.462. Plan on a vigorous turn them both off approach after ZAP download and sufficient reboots to verify neither
is running before beginning ZAP upgrade or clean install. Will have downloaded KAV in case of untoward results, but expect no problems because this plan conforms to the Kaspersky First method.
Operating System:Windows XP Home Edition
Product Name:ZoneAlarm Pro
