This forum post: https://forum.eset.com/topic/4672-eset-endpoint-antivirus-locking-up-windows-7-pro/page-2 is dealing with a similar lockup issue on Windows 7 and the last couple of entries refer to a Microsoft hotfix: https://support.microsoft.com/en-us/kb/2664888 I just installed the hotfix on my 2008R2 server (requires reboot) so will wait and see if this helps

I too am experiencing this exact problem. Have a 2008R2 server with File Security 6.0.12035.0 installed and system locks up every 3 to 5 days. No BSOD just frozen up. Is a VM and machine performance graph shows CPU usage jumps up at time of crash and stays high until I do a hard reset of the VM. Memory usage stays normal throughout and disk usage stops at time of crash. Windows logs show nothing, ESET logs show nothing. Thankfully this is not a critical server. No issues with EFS version 6 on 2012 servers.
