Startup errors on a 2015 13-inch MacBook Pro

This morning I had an issue where my 2015 MBP 13" started typing spaces on its own. I booted into safe mode, tried to blow out the keyboard (none of the keys were sticking or felt crunchy) and while I was at it, I did the latest updates (still on Sierra). It does seem to be working on now, but I’m also on my external kb and mouse.

Now I am getting these two errors on boot (see pix). I saw reference to this with kernel panics, but I’m not getting any of those.

The thought of malware crossed my mind, what are the best apps for that these days? I run that so infrequently that I don’t remember what I used last.

Most of my case, including keyboard and battery were replaced under warranty May 2018
