Unexplained Script File

Our website is having issues displaying search results (a longer conversation) but we also found this weird script file when inspecting any page: lly-It-withe-Lady-bore-Exit-way-lose-Macb-Beld-H.

We have no record of it, and we can’t even remove it from our server as we do not see it.

Any ideas?

We have tried removing the file, but it doesn’t seem to exist on our server.

Thank you.
