how to remove auto signature-"john appleseed name" imbedded in my computer

I do use  Malwarebytes - have for years which showed no problems.

Good news however. PROBLEM SOLVED. I thought about this and finally figured out what the problem was-- it was a "snippet" in the application "type it for me". I had looked there before in my list of abbreviations but I did not look in the examples that came with the original app. Maybe years ago when I got the application I looked through it but all looked good. I deleted it and no I think the appleseed -whatever it is - seems to be gone. I don't know what took me so long. I did look at this before in my list but not in the examples.

Type it for me, although 3rd party, is a really a very useful application which saves a lot of time when typing. I just missed this one thing in the list that came with it.

Thanks so much for looking into this as well.

This imbedded signature may or may not be a meme; it is text with a png photo of a signature. At any rate I have used text substitution many times and tried to change it to overwrite this and it does not work. I'll include a pix of it. All I do is press those to letters and this is what I get:

The signature is a png picture. And it comes with text, so maybe it is a meme? I was just guessing because I don't know what else to say to describe this. I did find that there used to be a John Appleseed connection with Apple early in its start. Here is a little of what I found:

"What's the connection between Appleseed and Apple?

• Appleseed's connection with Apple goes back to the start of the 1980s. Apple then was a very different company than it is today: it became a public company in 1980 but wasn't a buttoned-up, blue-suited corporation like IBM; it was a blue-jeaned, open-necked shirt, bearded kind of company out to make a difference.

This is why I thought this may be imbedded deep into the mac somewhere. There used to be something called

easter eggs" years ago where a certain trigger would bring up these little surprises. Someone in my online apple user group does not thing this is an Easter Egg. What then triggers this and why can't I get it to stop?

• There are a number of online articles about "Easter Eggs" and Apple. Supposedly Steve Jobs got rid of them, but I still wonder if he got rid of all of them. Here is a brief description, "Easter Eggs are little hidden messages, secret features or inside jokes that can be found on any platform in the digital sphere. There are no explicit instructions that lead to an Easter Egg, which makes it especially exciting when you stumble upon one at random." There are some examples online of Easter eggs. I did not see the Appleseed one in particular.

Still a mystery!
