A bug in the recent update of Symantec's Anti-virus software caused some windows-based PCs to crash, the security software maker disclosed Friday.
An update earlier this week to Symantec Endpoint Protection 12.1 antivirus software for businesses caused some Windows XP-based computers to crash repeatedly with a "blue screen of death," the company revealed on its Web site.
The embarrassment comes at a challenging time for Symantec, whose shares have lost about a quarter of their value since it warned of a pending profit decline three months ago.
According to Reuters, the company knows so far of about 300 corporate customers that have been affected, and about 60 consumer customers.
Customers reported it took Symantec hours to identify and fix the bug and that they needed to fix computers broken by the tainted update on their own.
Symantec blamed the glitch on software compatibility issues that arose after an update was released late on Wednesday. PCs could be fixed if customers manually removed the software from each disabled computer, it said in an advisory.
