EIDE hard drives often have a MBTF (Mean time between failures) of
400,000 hours. While any use contributes to wear, the value of frequent
  scans far outweighs the additional use involved.
Backups cause wear also, but may be even more important than virus scans.
I choose to scan daily and backup weekly.
