-/* This module detects applications from the Big List of Dodgy Apps,
- a list of applications that have at some given time been shown to
- interfere with the operation of cygwin. It detects the presence of
- applications on the system by looking for any of four traces an
- installation might leave: 1) registry keys, 2) files on disk
- 3) running executables 4) loaded dlls or drivers.
-
- At the time of writing, the BLODA amounts to:-
-
- Sonic Solutions burning software containing DLA component
- Norton/MacAffee/Symantec antivirus or antispyware
- Logitech webcam software with "Logitech process monitor" service
- Kerio, Agnitum or ZoneAlarm Personal Firewall
- Iolo System Mechanic/AntiVirus/Firewall
- LanDesk
- Windows Defender
- Embassy Trust Suite fingerprint reader software containing wxvault.dll
- ByteMobile laptop optimization client
-
- A live version is now being maintained in the Cygwin FAQ, at
