How Do I Know if AV Worked?

I have a schedule set up to scan my laptop at 4PM every Friday. How can I tell if this scan actually took place?

You can verify the logfile by going to AV → View antivirus events → press the ‘More’ button and go to ‘Tasks launched’.
The scan should be recorded there including it’s results. If it doesn’t show press the ‘current week’ button on the top to get more dates in the logviewer to show up.
