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

[-] stifle867@programming.dev 8 points 1 year ago

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.

[-] QuazarOmega@lemy.lol 1 points 1 year ago

Yes, that's a good point, being careful goes a long way, though exploits can really come from anywhere.

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

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?

[-] GnomeComedy@beehaw.org 1 points 1 year ago* (last edited 1 year ago)

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. ;-)

[-] neosheo@discuss.tchncs.de 1 points 1 year ago

How would you determine the configs that were modified? What do you mean put down?

[-] GnomeComedy@beehaw.org 1 points 1 year ago

Ideally you keep your configs in a git repo (like github). You know what's modified because you're the one who modified them. If you modify them - put that config file in the git repo.

As for "put down" I just meant copied to the system (from github) by your automation (like ansible)
