CPU usage for 'ESET Cyber Security Pro.app' only goes up to 1% at most, but is usually 0.5%. Looking at a fully updated Cyber Security Pro 6.0.14.0 on Yosemite 10.10.2 with a 2.3 GHz Intel Core i7, with Activity Monitor running side by side, the CPU usage does go to 2 to 3% (maybe more) when something needed to be scanned in realtime, but then back to 0.5% or less when there is no activity (this is for the esets_daemon process).

If you open Cyber Security and go to Tools > Statistics, under 'Antivirus protection summary' you can view what is being scanned in the background (any files being used by processes or Applications). With the CPU, the real-time file system protection is quite active even when you think nothing is being scanned which may explain that CPU activity. Permissions repair didn't solve the issue. However, I wasn’t able to install version 5 or version 6 and all I got is this non-descriptive error in the picture below.

So I decided to remove version 6 and reinstall version 5. However, version 6 now seemed to take more CPU (5-25%) even when nothing scanning. Issue didn’t resolve by downgrade but I resolved it by excluding some directories with huge number of documents (30k+) which I don’t need to scan.Īfter exclusion, EC seemed to run OK, so I decided to upgrade to version 6 again. I had version 6 installed but it was taking too long to scan.ĭowngraded to version 5 (uninstall 6 and install 5). I tried uninstall using included uninstaller, manual cleanups etc. I get the error message and installation stops. Installer gives me error message right after it starts “Validation of packages or something”. I didn't investigate further why this happened, maybe Eset support staff can review, it looks like the installer wasn't able to use the Temporary directory? Run ONYX utility and all the maintenance tools and reboot. Can't install Eset CyberSecurity on OSX 10.9.5 due to unspecified installation error
