It's adware and you should remove it
This is an ad for Combo Cleaner, but if you have something else, you can use that and still follow the steps to remove it.
I don't like MacKeeper at all. It gave me a case of the pop-ups and slowed my iMac to a crawl. If you have it and want to remove it... https://www.imore.com/removing-mackeeper-your-mac
My work machine uses F-Secure, but that might be expensive. MacWorld suggests Avast Free Mac Security as the best free anti-virus for Macs and Sophos as the best paid anti-virus. I honestly can't remember what I have at home, but it was cheap (probably free) and works well. I'll let you know later if you like.
BTW, this is all my opinion/research having owned and worked with Macs for 10+ years, but I'm really no expert. So if anyone with real expertise wishes to chime in and prove me wrong abiout MacKeeper or even Ishimotto, please feel free to correct the record!
Hey, I've worked with Macs since the iic and I remain clueless. I appreciate your help.

Anyone know what Ishimotto is and how it got into my Safari extensions? If so, is it dangerous, as I've read, or can I just trash it?
Also, is it possible that my Adblock extension has disappeared? It too used to be in my Safari extensions.
