Check Point has issued a set of updates which correct a compatibility issue with the latest Microsoft update.

The security firm has posted new versions of its ZoneAlarm Internet Security Suite, Pro, Antivirus, Anti-Spyware and Basic Firewall offerings.

The updates correct an error caused by the Microsoft Patch Tuesday update released on 8 July.

One of the four bulletins addressed a flaw in the Windows DNS component, but also resulted in an error which prevented ZoneAlarm users from accessing the internet.

Many ZoneAlarm customers, including several vnunet.com readers, were left unable to connect to the internet and were forced to uninstall the security update or temporarily lower the security level on their ZoneAlarm applications.

Check Point promised yesterday that a patch was in the works, advising users to keep an eye on the site for the updates.

By Thursday evening updated versions of all five applications had been posted, along with a list of recommended actions for those who do not wish to install the updates.

All five of the updated applications can be downloaded directly from the Check Point support site.
