The 'Collect Logs' feature is for when Trend Micro Support personnel are trying to trouble shoot a specific problem with the Mobile Security app. The information collected with this feature are those only relevant with the Security Application only.
The logs that will be exported during this process will only produce a text file that our team interprets in the back end. It only consumes 32kB of storage (most selfies are 3MB which is way larger).
Just ignore this feature unless you have been instructed by one of our supports to extract logs.
