cant start quick scan - custom shows it running for 2 days but no signs

Can't start a quick scan. If I try 'custom' it shows that quick scan has been running for 2 days - but there's no other indication, nothing to stop.

Full scan, update, etc all ok.  Reboot has no effect.  Support diagnostic shows all ok.
