I'm certainly not convinved about that either, but we should make a test on
a VM at some point.
Sophos AV has plugins into for example the explorer (I assume - most AV
does, haven't used Sophos specifically myself), which may be done with
extra DLLs loading along with user32.dll (runtime linked) or something like
that. I just want to be sure we exclude that possibility.
