Again, if the ASLR setup has been changed via registry, I wouldn't bet
that the uninstallation of the application that changed them to reset
to the defaults (if it was indeed AVG,).

Any ASLR aware library can be mapped to rather low adresses, but that
usually means it couldn't load to where it originally wanted to go.  MS
actually uses this to force non-ASLR aware images to random addresses if
the corresponding option is set.

If mandatory ASLR and bottom-up forced randomization got switched on,
that will probably result in the same behaviour.  1803 should offer
(most of) these options from some GUI tab (Security Center / App Control
/ Exploit Protection), I don't remember what 1709 had available there.
The defaults are all "on" except forced ASLR, I think.

Achim.
