Microsoft on Thursday lashed out against Google Chrome Frame--an Internet Explorer plug-in that supplants IE's rendering engine with Google's.

The software maker, in a statement, said users are better off moving to a later version of Internet Explorer if they want the latest technology as opposed to using Chrome Frame.

"With Internet Explorer 8, we made significant advancements and updates to make the browser safer for our customers," Microsoft said. "Given the security issues with plug-ins in general and Google Chrome in particular, Google Chrome Frame running as a plug-in has doubled the attach area for malware and malicious scripts. This is not a risk we would recommend our friends and families take."
