Strange behaviour of installer of Avast Free.

Hi, sorry my bad english.
My system is Windows 10 pro fresh installation.
I want notify a strange behaviour with installer of Avast.
When i launched “avast_free_antivirus_setup_online_e2g.exe” i got message “Stub cannot run installer”.
However i had also a second installer downloaded a few hours before named “avast_free_antivirus_setup_online_a2g.exe” (note “a2g” in lieu of “e2g”!?!).
Nothe that i have not renamed in this way this second file. It is the name of download.
This second installar worked fine!
I have read of other users with same problem “Stub cannot run” when run uninstallation under windows 10.
I hope to be useful.

Gianluca.
