Possible virus??

I have a laptop with Linux Mint 20, Ulyana, and lately it has been invaded by a square shaped speaker or sound icon occasionally flashing on and off on the bottom of my screen. I have tried clamav, autoclean, and autoremove but so far no luck getting rid of it. Has anyone else seen this annoying icon popping up on their screen? Or any7 suggestions on how to fi9nd it and delete it? It's currently flashing on and off as I type. Thanks.
