avast! Backup 5994 cannot send its own data correctly

The backup is dropping when trying to send the app data and it cannot go further.
com.avast.android.mobilesecurity_5994.zip

What is the issue it reports?

None. Just hangs and stays there…

can you get me a log (ADB logcat)?

to create a log please proceed as follows:

a) Create an empty file called “avast-debug” on your /sdcard root directory (on Android 4.x phones there might be a user subdirectory in the sdcard path - if yes use that)
The “avast-debug” file will stay empty, as it’s existence is only a flag for the app to generate more detailed log output, which you’ll send later.
b) REBOOT your phone
c) Now Avast generates a lot of log
d) Try to reconstruct your problem
e) After that, open Mobile Security or Anti-Theft (depending in which product your problem occurs) and go to the feedback screen (About)
f) Check “Send system log”
g) Create a case there giving your email address and mention this conversation as well as a short description of the problem (maybe someone else will get the case)
h) Then remove the avast-debug file again
i) REBOOT your phone
j) Everything back to normal

Thank you!
