Do you mean YandexPortable_16.11.1.673_on_Chrome_54.0.2840.673.paf? The version you use actually has some official bugs, that's why they released the next version quite quick after that.

But we did leave these executables in the "App\Browser-bin" folder:
service_update.exe
yupdate-exec.exe
just in case Yandex support clean auto-update like our Opera or Vivaldi browsers.

Anyway, you can just delete those executables from the folder to prevent it to run in the future.

And thanks for your feedback, we will leave out those execs. on our next releases.

Regards,
Ronny
