Yeah I was stupid enough to ignore a Firefox warning that said website's cert was expired ><

This damned thing keeps popping up. Malwarebytes and quick Windows Defender scans found nothing. Had the full scan running earlier but had to force-restart PC when windows taskbar would not respond (could alt-tab between active programs but not use taskbar), and still nothing.

Am thinking run CCleaner but never seen it recommended in IT security. Any suggestions? Thanks!
