Hi Cathy,

Real-time scanners should catch all malware that can directly affect 
you. But it may decide not to scan that 500 MB zip file for performance 
reasons. That file may contain a virus and a scheduled scan will detect 
that. But there is no direct way you can be affected by that virus 
without extracting the file, at which time the real-time scanner will 
protect you.

>>From discussions with the anti-virus vendors during various crises over the years, I've learned that the real-time scans are optimized for speed, while the scheduled scans are focused on thoroughness.  This means, disturbingly, that malware can elude the real-time scan, yet be caught by the more-thorough scheduled scan.  Hence the anti-virus vendors continued recommendations to run weekly scheduled local scans on all computers.
