I'm using Spybot on my Win XP home PC. I've been meaning to ask about
this odd behaviour for months. When it finishes the scan (which it
does at a reasonable speed), there is then a very long delay, maybe
10-15 mins, during which it appears to be doing nothing, but the scan
does not yet report the finished status. Then it eventually does, and
I proceed as usual (typically just removing 4-8 tracking cookies).

What is going on during that long period please?
