Hi, would you know an efficient and privacy friendly Ubuntu antivirus ?

Hi, I recently switched to Ubuntu but the file manager (Nautilus I think) is not practical at all. I would like to be able to : 1-Edit the column on the left to keep only the "My documents" category  2-To create a shortcut on the desktop to the "My document" folder and also for other files. What would you recommend ? Thank you

Hi, I would like to find a bank or a privacy friendly payment method, not able to review every purchase I did. I thought to several alternatives : 1° Find a bank explicitely dedicated to data privacy (names ?) 2° Open an account in a bank located in Switzerland as it's the world strongest regulation for data privacy ? 3° Use a masked card or virtual number card ? 4° Find a data privacy friendly online payment platform (name ?) 5° Use crypto or cash lol ? Any advise about these options ? Would you recommend other options ? Also I'm located in Europe if you know specific offers in the EU market related to that concern.
