Microsoft issued a speedy update to its Security Essentials on Sept. 30 after receiving notice from its users regarding errant malware detection by the security product. Apparently, the fix didn't "fix" everyone.
Google decided to issue its on update on Oct. 1 to repair damaged Chrome installations that weren’t repaired by the Microsoft update. “The Chrome Stable channel has been updated to 14.0.835.187, and the Beta channel has been updated to 15.0.874.58. These updates should help repair Chrome installs that were broken due to the issue with Microsoft Security Essentials”, Google said.
In a Sept. 30 blog, Google engineering manager Mark Larson wrote, “We learned that the Microsoft Security Essentials tool began to falsely identify Google Chrome as a piece of malware (PWS:Win32/Zbot) and removing it from people’s computers….We are releasing an update that will automatically repair Chrome for affected users over the course of the next 24 hours.”
“If Chrome is working correctly, you don’t need to do anything. If you’re unable to launch Chrome or load new web pages, then you may be affected”, the blog added.
