The downloading indicator continues to run in the 'green' indicating that it is downloading email...it does not download email though it seems to never stop so indicating. By clicking a given email that was downloaded on or before 2-2-16, it can be read it but I can receive none past said date. I run regular scans with AVG and they seem to be successful in keep my windows 7 and Thunderbird clean tho today AVG found and ISOLATED 'Crypt', a trojan horse. That seemed to have NO effect upon my problem. This seems to be on one computer ( MSI ge60 i5-3230M intel core) as my others do not have that problem. Has anyone had a similar experience and if so, what is it?
