Sure, just send it to my email.

Sent. Thanks.
Hi,
the problem is that the log gets cleared after reboot so there is nothing in the log you sent 
If you start some procedure in ROM Toolbox which reboots the device after, for example, 1 minute, I need a log from that minute. Preferably create an empty “avast-debug” file on your SD card and reboot your device to enable more logs from AMS.

Hello!
i have a nice “make-a-log”-step-by-step guide:
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
although you might want to send the log directly to mr. Havlicek instead of creating a support case.
Hi Werner,
This “make-a-log”-step-by-step guide could go on the avast! Mobile: FAQ - General support page, https://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=1034.
Don’t know exactly what the sub-title in the ‘Other Questions’ section of the support page might be ‘How do I create an avast-debug log file,’ perhaps.
How?
Forget it. Manage myself.
Create a txt file in the computer, moved to the sdcard, rename removing the extension.
Well, the phone freezes and I cannot collect any of the aLogCat data.
I need to use QtADB for that.
In my computer, the latest lines in the log are:
Hm, there is nothing from AMS there. After creating the avast-debug file, do you see any messages from AMS during normal operation? I’m pretty sure you can recognize it cause there is going to be a lot of them.

Indeed, seems not to be related. I was testing the AMS beta and the problem arrived. I’ve thought they could be related.
The developers of Rom Toolbox have already put the issue in the bug list. Now I have to wait 8)
Thanks Filip.
OK, let’s see how that goes
