Emsisoft 9 IS... A CPU 'Runaway'?

Recommended Posts

I have Emsisoft Version 9 IS running on a standalone Windows 8.1 64bit PC machine. I have seen over the past days where Emsisoft EIS will start ramping up the CPU usage, from its usual 1+% all the way to 46% constant CPU usage and sometimes more. I can always tell when Emsisoft is doing this, because all the system and CPU fans start slowly ramping up as the CPU is being more and more taxed into service. If I do nothing about it, this problem will go on for hours without stopping.


I am forced to reboot the PC machine, only to see this High CPU usage problem start back up again, in about an hour or so, even if the PC is simply idling. And during this time, the PC isn't being used for anything but mail-reading or light web-surfing. No other processes or heavy application usage is taking place, and causing the CPU to work that hard.


Any ideas as to why this happens?  Here is a small display of Task Manager when this problem is going on:

Okay, I was asked after this message was posted to clarify something: EIS was not actively 'scanning' the files in the system at the time of its high CPU usage. It was simply sitting there in the system-tray, saying the system was 'Protected' as usual, as well as the time it last Updated. EIS 9 itself still works fine, and doesn't seem to be hung-up on anything when this problem occurs.  The LOGS show normal activity throughout the day and no 'suspicious' activity in the system.

it looks like a application on your system triggers permanently behaviour blocker events.


We need debug logs to identify this application.


Please download the file from and unpack the ZIP on your computer.


Now please run the script enable_debug_output.bat as Administrator and reboot your computer.


Lets run the computer for 10 minutes with the high CPU usage. Is this done please run the script disable_debug_output.bat to disable the logging. Restart your computer again.


Now please add the folder C:\ProgramData\Emsisoft\Logs to a ZIP file and send me this file to [email protected] with a hint to this forum topic here.
