Issues detected but no threats found

OK...I've recreated this.

The 'issues' are nothing to worry about - it's just naff that the frontend blurts out 'Issues detected' without allowing more detail in the user interface.

The 'issues' will be things like corrupt files, encrypted files, or anything the scanner has a problem with. 99.99999% of the time they are no problem at all.  It's expected behavior (feel free to debate that it's really not the scanners fault).

You said you ran a scan of the Downloads folder.  Therefore...

1. Start the scan of the Download folder again.
2. While that is running open Console (from Spotlight search for 'Console').
3. On the left side of Console select/expand 'Sophos Anti-Virus' > Scans > theNameYouGaveTheScan > then select the most recent date and time.
4. Flick back to SAV and watch for the 'Issues detected' warning to appear.  Then stop the scan.
5. Flick back to Console and 'reload' the log.
6. Look through the output of the scan and note any mention of 'Corrupt file:...' or 'Encrypted file:...'
   

Any file the scanner has a problem with (for a genuine reason) cause an error and SAV (on the frontend) displays 'Issues detected'.

These really are nothing to worry about - you're safe. :smileyhappy:

If you want another method to the above (maybe this is simpler) you can open Terminal (search with Spotlight for 'terminal'), run...

sweep ~/Downloads

 Note: for me to get some issues I ran..

sweep ~/Library/Containers

 ...which is pretty quick to complete.

...and wait for the scan to complete.  The summary will mention 'X errors were encountered' 'X encrypted files were not checked' etc.  Example:

28332 files swept in 1 minute and 43 seconds.
57 errors were encountered.
1 virus was discovered.
1 file out of 28332 was infected.
