⯈ ESET Mail Security for Lotus Domino 6.5.14026
⯈ ESET Security for Sharepoint Server 6.5
⯈ ESET NOD32 Antivirus/ESET Smart Security 9
This issue DOES NOT affect the latest versions of our products including the latest ESET Endpoint Antivirus/ESET Endpoint Security – 6.6.2089, 7.2 and 7.3 and ESET File Security for Windows 7.1.12008 and customers using the latest versions are not affected in any way. This issue relevant to the impacted versions listed and described above. Newest versions of our products are NOT affected.

This method fails and our modules in older, legacy versions, are declared as untrusted and therefore are not loaded. This mechanism ensures that no untrusted library is loaded.
As a result, the affected versions fail to load modules (Firewall, HIPS, Updated, Device Control, Web and Email protection) and are not functional, therefore the protection is not functional.
For versions older than 5.0.2271.x symptoms are:
For versions 6.5.x symptoms are:
If they are managed by our ESET Remote Administrator or ESET Security Management Center, they will fall back to the respective parametric group and report an alert as not being activated and the antiphishing module as not functional.
