maniel 0 Posted May 26, 2017 Share Posted May 26, 2017 (edited) Hello We're migrating to ESET Endpoint Antivirus from Kaspersky, when I deployed agent on a few machines a week ago, some of them are unusably slow, hang, problem seems to persist after AV uninstallation (leaving only Agent), in one case problem still exists after agent uninstallation, the symptoms are similar to WFP bug in windows 7, but it happens on Windows 10 (x64) machines symptoms: programs freeze programs taking much time to launch (IF launching), suddenly launching en masse (or not) after a period of time after multiple attempts to launch, like something unlocks cpu and I/O (hdd light blinking occasionally, like in idle) load is low, system doesn't seem to be under load 7zip hangs when unpacking anything, like it goes to 99% and then slows down to B/s Edited May 26, 2017 by maniel added a symptom Link to comment Share on other sites More sharing options...
Administrators Marcos 4,705 Posted May 26, 2017 Administrators Share Posted May 26, 2017 Agent does not contain a driver that would hook the file system and affect 7z when unpacking files for instance. If possible, configure the system to generate complete memory dumps and generate one as per the instructions at http://support.eset.com/kb380. When done, compress the dump, upload it to a safe location and pm me a download link. In the mean time, collect logs with ELC as per the instructions linked in my signature and provide me with the generated zip file for perusal.

maniel 0 Posted May 30, 2017 Author Share Posted May 30, 2017 it turned out to be Windows Defender related problem, it made computer unusable in this case, it went away when i manually disabled windows defender, but we're having multiple reports of unresponsive machines after deploying EEA, raging from 32bit windows 7 to 64bit windows 10 Link to comment Share on other sites More sharing options...
