That looks like you have some malware installed on your computer.
We just provide a .csv file… it has no ties to the application used to open it.
As you can see from the first image, an application called File Viewer has been set as the default application to open .csvs on your device.
You should consider running a malware scanner (Windows has one) to get rid of the malware, and try right-clicking the .csv file icon and selecting ‘open with’ to choose another program to open .csv files by default.
I’m no Windows expert but that should get you back on track.
Thanks,
