Symantec software update causes widespread PC crashes

A bug in an update of Symantec Corp's anti-virus software has caused some Windows PCs to crash late this week, making machines inoperable until they were serviced in an embarrassing episode that angered some customers, Reuters has reported. The company acknowledged the problem, saying that an update to its widely used Symantec Endpoint Protection 12.1 and Norton anti-virus software for businesses caused some PCs running Microsoft Windows XP software to crash repeatedly, showing what is known as the "blue screen of death." 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.
