Hi,
we've the same problem here. In our company we have round about 250 clients with ESET v.6.2.2033.1.
40-50 clients have problems with "freezing" (Win 7/8.1/10). We don't know why. Several clients, several OS, several Hardware. When we disable ESET on the workstations all is working fine. We've replaced the "network.dll" as described here: hxxp://support.eset.com/kb2567/.
Regarding the hotfix: It's not possible to execute the Hotfix on Windows 8.1 or 10. Is there another Hotfix available or is it not necessary.
If we downgrade the certain clients to version 5 all is working fine.
What can we do?
