Just to add my two penceworth
We pushed out the 8.1 update to 250+ computers across 13 different customers
Prior to this we had had no reported incidents
Post update we have customers reporting ESET pop-ups across all sites
The firewall rules on all sites have no restriction on outbound traffic so it is 100% not the firewall producing the issue
I would like to suggest ESET support stop trying to blame the issue on end users and take a look at the overall picture!
We have been using ESET for nearly a decade and have been incredibly pleased with it
But this issue is affecting EVERYBODY and is causing serious customer unease -nobody likes getting a frequent pop up telling them their system protection has an issue
