re file scanners I only see vague references to Norton (Symantec) being 
bad.
But I am not sure yet. Indeed the worst problems are winsock related.

For now we just block this McAfee service, but we also had reports for 
Norton (Symantec) AntiVir to limit the usability of our app.

Generally, every NT Service that starts with "Norton" or "Symantec" is 
considered evil. But not in detail yet.
Of course certain firewalls also, like zonelaram, but you have to search 
the cygwin mailinglist archives for exact reports.

AntiVir or F-Prot on-access virus scanners or internet updaters are 
considered well-behaving.
