7 Of The Best Antivirus Programs for Ubuntu


When it comes to Ubuntu, it’s a hackers paradise as well as hackers hell. Even the best programmers or hackers can’t create viruses for Ubuntu.

Infecting an Ubuntu system with a virus is as difficult as fighting a military man with a knife. So, the theory of Ubuntu Antivirus sounds a bit lame.

But when you look at the bigger picture, every Operating system is vulnerable. Attack-vectors, payloads, malware are every man’s fear. Everyone wants to be safe, and when it comes to real life, no one really is.

Linux Operating systems that use the Samba server or have external storage common to a Windows operating system are inevitable to virus circulation.

A remote contact with a Windows operating system can be a disaster, still, Ubuntu’s are being targeted by the Hackers directly these days.

This may not be frequent today but it is certainly growing at an alarming rate.

Considering even the slightest possible threats to Ubuntu Operating systems, we are going to discuss the possible solution to our virus problems. Best Antivirus for Ubuntu that exists.

First of all, let me make one thing clear, this list is for the users who are servers or use servers. Mainly interacting with a network and some other system is what makes a machine vulnerable to exploitation.

A home user with no access to a network or any external interaction is safe and sound. But users with multiple access and connections do require these Antiviruses.

Although your preference may differ from ours, we will just brief you with the infamous and certified.

All the Ubuntu Antivirus or Windows Antivirus don’t work the same way. Some have flawless scanning accuracy while others act well at removing the virus. Some have high precision while others have high speed.

Every Antivirus has its own choice of weapon and quality of the weapon. But we are going to talk about renowned Ubuntu Antivirus with present validity.

With Kaspersky being accused of tie-ups with Russian spies and Bitdefender being allegedly shut down, we have narrowed down our list to the legitimate ones. Let us talk about them.

Note:- I have written a post for people looking for the best laptop for architecture students, do read it If you are interested.
