Situation: Spybot-S&D may locate a malware infection.

Experienced: once the file was deleted, it's difficult to get an estimate on how old the infection might have been.

Expected: add file age (created, modified) to log file. Include size and MD5 while we're at it.

This would be a great feature :)

Isn't maybe MD5 (not MD%)?
Does that adds when the file was removed (or backed up)?

Ah yes, MD5... I recently switched my keyboard llayout again, switching the shift state of the top row ;)

That information is added immediately when the scan report is created, independent of fixing.
