Full story: Tech giants unite to thwart web hijack risk
Hundreds of thousands of people who use the ZoneAlarm firewall to protect their PC have been locked out of the internet by Microsoft's latest round of software updates.
Microsoft released four high-priority fixes as part of its regular Patch Tuesday update, one of which left ZoneAlarm users without web access, reported vnunet.com
It is thought that the MS08-037 fix is designed to plug a vulnerability in the way that Windows handles the internet's system of addresses, which could have allowed hackers to reroute web users to malicious web pages. The patch appears to have been responsible for "compatibility issues" with ZoneAlarm.
A spokesman for ZoneLabs, the company that manufacturers ZoneAlarm, said the problem had come to light when US users began downloading the Microsoft code.
Zonelabs posted this advice: "Sudden loss of internet access: Microsoft Update KB951748 is known to cause loss of internet access for ZoneAlarm users. We recommend that users uninstall KB951748 using "Add or Remove Programs" until the issue is resolved."
