How do I change icons for the mobile view and search results?

[blueglass22]

I have changed the icons for my website, but it seems like there's a hidden AbanteCart icon which shows up when sometimes on mobile screen and search results.
I have checked the images folder in Server File Manager but I can't find it. I hope someone can locate it for me. I have added a screenshot.
