I get this error message when logging into Gmail using either Google Chrome or Internet Explorer but not with Firefox. This just started. I also find that when I do log into gmail it has me in HTML mode even though the settings are correct.
I have run Virus Scan and Spybot and found nothing wrong.
What is up and should I be concerned?

if u have runned scans i would go ahead and go on the website but be careful not to click on any pop up adds
