Bizarre, but true. Version 2015.10.0.2208. Says this is the current version.
Scan–Scan For Virus–Settings–Give a name for scan–Scan all files checked–Scheduling “Schedule this Scan” checked–Daily, various days checked and 02:00 scan time. Nothing appears. It won’t take to scheduling a scan.
Note: under Scan for Virus the drop down box only has “boot-time scan” as an option. Nothing else shows. I checked Avast on another computer and clicking on the drop down box has several different options including full scan and quick scan. So clearly there is something wrong with my installed version.
