How do I get rid of Psoraiasis message "<app> will damage your computer" ?

Please read: About those "<app> will damage your computer" messages - Apple Community.

I suggest that you try Malwarebytes for Mac to detect and remove any malware from this computer.

I couldn’t find more information on associated apps or processes for these. That is potentially suspicious, imho.

I could find info on these. Splashtop Streamer is existing software for remote access, with a website. I’ve never heard of it before, though. I would be reluctant of giving remote access through unknown software. But it seems you installed or used that, way back in 2016. Their site says that they have newer software. I would suggest to delete these files if no longer in active use.
