iMac Cleaning Popup

Lately, a popup appears upon opening iMac that it needs a cleaning, I don't use a cleanup program.

Hello,

It sounds like a bit of malware. Try downloading and running Malwarebytes for Mac.

Let us know if that corrects it.

That is a scam. Ignore it and then scan your Mac for Malware. Like Cory said Malwarebytes is a good choice. Update it before using it.
