Ghost link absolutely nowhere to find

After working with an Excel file for quite some time, like data modelling files, when opening the Excel, there's a message on the bottom right corner of the screen which says Linking: Vinculos.xls

I'm worried that it's a malware or sth. I should state that this even happens on files that I build from scratch on my device and I've searched on my local storage and this file does not exist.

I've looked everywhere, you name it. Cells, Add-Ins, Named Ranges, Macros, Pivot Tables, Conditional Formatting, Data Validation, Links but I couldn't find the Vinculos.xls file which my file is linked to.

Could someone please help me find this goddamn link?
