windows defender issues? & other AV issues

[Lagi Pittas]

A POS system that I wrote saved a few arrays and text on exit. It worked
beautifully in  99.9% % of the time but every so often the user would start
up and the file was corrupted some how - I  saw the tilde file (exactly as
word does (used to do it?), when view extensions for known file type was
enabled in windows.

The thing I couldn't figure was that people using it for over 2 years never
had a problem, another shop that had three of my  POS systems NEVER had a
problem there were basically at most 5-7 sites that had the problem -
rarely (once or twice a year  - then never again) but two machines were
corrupting every month or so it seemed). I checked to see if they switched
off without exiting - but I know that in 99.99% of cases you could do that
without corrupting.

All the machines run windows 7 embedded and of course I switched off
updates (if it works today it will work tomorrow - I threatened them with
death if they installed anything or used the internet on it). There was  no
rhyme or reason to the corruption, as one of the shops had 2 machines
bought at the same time and the one was corrupting consistently and the
other wasn't. In the end I just created another table in the sqlite
database and saved the encoded  arrays in there - never a problem since.
Lesson learned (by me at least) it's not worth the aggro, the coding is not
that much more involved so why bother unless it's for my  own use as I have
full control? Although I have teamviewer on each machine - talking somebody
through connecting the device to the internet after they have changed ISP
or other reasons meant too much wasted time explaining what and where a
status bar was/is
