After installing 5.0.2126 the following issue occurs: Users of Citrix services that exist on external systems (on the internet) no longer can connect. Environment: - Windows XP - Proxy server for all internet connections - Two browsers: IE and Mozilla Seamonkey - ESET Endpoint Antivirus, almost default config, HTTPS scanning not enabled Users can visit HTTPS pages OK, can visit the login page of a Citrix server and login, get the page with available applications, click on an application. .ICA file is downloaded and will be run by the Citrix plugin locally installed on the system. Plugin starts OK and attempts to make connection, this fails with a popup: Cannot connect to the Citrix Xenapp Server. SSL Error 4: Attempted to connect using the ( TLS V1.0 | SSL V3.0 ) protocols. The Server rejected the connection. Looking in the proxy log it appears that a CONNECT was done and serviced OK. After reverting to ESET 4.2.76 this problem no longer occurs. What is happening? Is ESET 5.0.2126 snooping on SSL traffic even when this is not enabled?
