I am running Freeware version on XP SP3. When I try to update I get an error message Could not connect to update server. Check proxy settings. I don't think I need to run a proxy. I am running a laptop at home using wireless connection. Emsisoft is included as exception on firewall. Turning firewall off makes no difference. I am having the same problem with other malware detection programs since being infected by a trojan. Since infection additional windows open when I use internet. Not detected today by Emsisoft. Any ideas how to resolve update issue?
