I searched the forums and could not find this exact problem covered anywhere.
The problem is when I scan large files. In this case I downloaded the trial version of VMware workstation v12 from the VMware website. After the download completed I scanned the file (file size: 306,299,040). The method being by right-clicking the .exe file and the select "Scan with ESET Smart Security". It didn't seem to scan anything and immediately show scanned successfully.
Please see attached screenshot.
This had happened before with large files but now I'm thinking something might be set incorrectly, a file that large shouldn't scan in the blink of an eye.
Any help would be appreciated.
