When I downloaded a file either in Gmail or Yahoo Email, it always ends up failing due to virus error. It happens to IE10, Google chrome and Firefox after I upgraded my laptop to IE10 and the latest version of Gmail. The laptop runs W7 Ultimate SP 1 with SuperAntispyware and Microsoft Seccurity Essentials. I use Superantispyware on demand-only for long time and quite happy with it. I don't remember exactly why MSE is there. I do notice once in a long while, MSE reports some virus errors.
I ran the same downloads from work computer using Gmail/IE9 and Yahoo Mail/IE9 and got no problems.
Each download appears taking a while on the initial downloading before announcing virus error. Any types of files get the same fate.
Same problem is still there after the uninstallation of Google Chrome. (Google Chrome was added after the IE10 upgrade from IE9).
Thanks for your help!
