I have a primary email account @ comcast. When I place the cursor over a received email it shows the sender and ISP, such as @yahoo.com. Within the last week some spam emails continuously show "loading" instead of of the other info. Whether I put this in the spam folder or trash can it continues to show "loading", even much later. I will not even view source on these. They are deleted immediately.

Is his more likely to be a new virus or a result of my manually adding previous spammer IP addresses to my blocked zones?

Am running Free Firewall & Antivirus

Thanks much,
