Trend Micro for the phone made me format my memory card

I have an LG K20.  It's software Android version 7.0 encrypts the memory card so that if someone jacks my phone, they can't get the data off my memory card by removing it and plugging it into a computer.
I've scanned my phone before.  I did not initiate this scan.  I was running a game.  I was switching from data to wifi when I saw it.   I switched to wifi, then I clicked on the notification so it was running on top. (It was making my game laggy anyway.)  I did not watch it.  My phone went to sleep when it was done.  When I woke my phone, it had a notification that I had to format my memory card.  I pulled my phone apart and left the battery out, cleaned my phone's inside, and then put it back together and restarted it.  It still had the format notification. I hooked up my memory card to my computer and it said that I needed to format it.
There was no virus on my memory card.  The only things I know was added to it since the last scan was some pictures I took (or screen shots).  I am lucky that I backed up my memory card on a hard drive that I have.  That was time consuming because when you try to move too much off the phone it freezes and you have to restart it.

Welcome to the community, mail_me_33611

Thanks for asking here.

We understand that you had some trouble with your memory card. The Trend Micro Mobile Security app do not have any capability nor feature that will ask you to format your SD/memory card. As far as I know, you will only get that notification if your memory card do not match the System File requirement of your phone. 

I hope this helps.

 Have a wonderful day!

Trend Micro did not ask me to format my memory card. What happened was Trend Micro activated while I was running a game and had the phone plugged into the wall. I stopped the game and let Trend Micro finish its scan. (Scans are more important than games.)  When the scan finished, I woke my phone and was unable to access my memory card. I had used my memory card recently to view the pictures on it (like less than an hour before).

There is nothing that proves that Trend Micro caused the condition that I was unable to read my memory card.  It just is a big coincidental that it happened at the exact same time. What I think happened is that my phone lost the ability to understand the encoding.  My memory card was encoded so that if you wanted my data on it, taking it out of the phone would not help. Without the understanding how to read the card, the card looked like a new unused card to every device. It is not unreasonable to think that Trend Micro might have stored something in the same memory place that my phone was keeping its understanding of how to decode. With no  way to read it, formatting my memory card was my only option.

I had had some problems before this happened. Some pictures, when I viewed them on the phone, I would be able to see them and then they would turn black.  I saw the whole picture before it turned black. When I viewed them on the computer, the bottom half would be black.  So maybe Trend Micro did not cause this.

My fix is to not encode my memory card.  Nothing on it is that vital, and if it is, I will move it to my phone's memory.
