Excluding process from scanning makes only a little difference. Also I doubt that it's related to file execution. IMO it's file Open that causes the problem. If I right-click on file, symptoms are the same: 30+ seconds till right-click menu appears and during that time ekrn,exe using one CPU core. If I then select Properties from righ-click menu whole thing happens again. So it's not just program startup that causes the problem.

I've tested different settings changes and two that help are: adding utorrent.exe to performance exclusion or disabling scan on file open option in real-time system protection. Other options disabled or enabled don't make a difference. I checked what's happening in background using ProcessMonitor and it seems that ekrn.exe is performing same action again and again for cca 30 seconds when that executable is accessed or run.

Thanks for suggestion. I tested qbittorent in past but prefer to use utorrent instead.

I run as limited admin (UAC at max). I don't use other tools. Execution is not blocked by Windows or it's mechanisms but by ESET. It happens only first time after ESET install (I tested it twice). After first time blockage uTorrent later can be run, it just takes cca. 30 seconds to start.

After installing latest version of Eset Internet Security, I have problem running uTorrent desktop application. At first run I got attached error message, all later app startups are really slow ( 30+ seconds). If I pause protection, uTorrent starts normally. Please give me instruction what data you need to help you troubleshoot this problem. Regards.
