Computerworld reports that Microsoft scrambled earlier today to revise an antivirus definition file that deleted Google's Chrome browser from users' PCs.

Storms was referring to the battle between Microsoft's Internet Explorer (IE) and rivals, including Chrome, for usage share. According to data from one Web metrics firm, Chrome will pass Mozilla's Firefox as the second-most-popular browser by the end of this year, pitting Google and Microsoft for the top spot.

Chrome users began reporting the specious detection of the browser early Friday in a quickly-growing thread on a Google support forum.
