I'd recommend upgrading to ESET Security Management Console which resolves threats automatically if they were cleaned without an error on clients. According to the screen shot, you have ERA, the predecessor of ESMC, installed.

Something is blocking the communication, probably an issue between your machine and your ISP, or between your ISP and ESET's servers. I'd suggest contacting your local customer care; they should be able to connect to your machine remotely and troubleshoot the issue.
