Privacy friendly Ubuntu antivirus ?

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

Again, seriously question why you need this but you could look into ClamAV. If you're coming from Windows you're going to be in for a shock if you blindly try and adapt every concept from Windows straight to Linux.
- It's not a bad thing to have an antivirus, especially now that we see more viruses made for Linux specifically. I still don't worry much myself, because the number isn't that huge, but if there was an easy to use antivirus GUI app I think I'd try it
  
  Anyone is welcome to install an AV on their device if they so choose. I was more alluding to the fact that there are many things you should be doing to prevent malicious programs from running on your computer in the first place. By the time it makes it onto your system you're really just hoping that an AV would happen to catch it.
Clam
AVs in Linux realm exist mostly for scanning windows stuff for email attachments, shared storage, etc.
I recommend this video from Rob Braxman titled Why an Antivirus Does Nothing for You, just came out recently: https://invidious.flokinet.to/watch?v=mE7CCZCgRB8
You're pretty save without an Antivirus on Linux (we're just 3%, not worth it for hackers), but if you need to check files, VirusTotal is your friend.
You'd be better served learning how to setup and use:

backups (and test them)

automate your reinstall (see ansible)

firewalld (RHEL/Fedora) or ufw (Ubuntu)

fail2ban

SELinux (RHEL/Fedora) or AppArmor (Ubuntu)

disable SSH via password, use keys only

adblocker (like ublock origin) - credit to whale@lemm.ee for the idea below
- Permanently Deleted
  
  No, most desktops behind a NAT probably dont need fail2ban (though it wouldn't hurt).
  
  Everyone's security profile/needs are different.
  
  The point is that list does a hell of a lot more useful than ClamAV

  This also assumes they know how to tell if it is exposed or not.
  
  I normally setup fail2ban as soon as I know something exposed to the outside.
- For the automating of reinstalls what do you mean?
  
  Is it just a playbook that installs the distro, them installs the same packages, and then restores things like /home from backup?
  
  That, and:
  
  put down config files that were modified
  
  enable/start services that were installed
  
  modify the firewall to open necessary ports
  
  Basically: put everything back as it was right before the ransomware encrypted your system on you.
  
  Then of course - fix what you did wrong that got you compromised. ;-)
