Windows OneCare labels Gmail as malicous

The problem began cropping up last week when OneCare-enabled users that visited Google's Gmail website were repeatedly warned that they were infected by a virus called "BAT/BWG.A."

Microsoft reported that the problem occurred after Google tweaked its Gmail site last week.

"Windows Live OneCare customers may have recently experienced an issue that incorrectly flagged files related to Google's Gmail service as a virus," a Microsoft representative said. "This was a limited false positive issue with our anti-virus protection."

On Sunday the company issued a new antivirus signature that resolved the issue, the spokesperson said. The company hopes to learn from this mishap to improve its security product in the future.

"We are reviewing our procedures and processes in order to minimise the occurrence of further false positives and apologise for any inconvenience this may have caused our customers," the spokesperson said.
