I have BitDefender Internet Security 2011 - Trial edition. I have uninstalled all my previous anti-virus and firewall programs. I have the latest flash player version and am using Chrome.
When I go to upload in Gmail or even a generic upload site it fails to upload. It states "Attachment failed. This may be due to a proxy or firewall."
I then disable all of the Bitdefender services including the firewall, to no avail it still does not work.
