Best Antivirus For Linux

Today’s article is all about the best Antivirus for Linux. But if Linux is so secure, why do we need to have an Antivirus, right?

You’re right! However, Linux powers more than 70% of the web servers in the world. And hackers are highly motivated to create powerful viruses to penetrate those server security systems. Though it’s not as easy as it is with Windows, given the default security setup of Linux, it’s also not impossible.

An accidental execution of a script can infect your system. And that’s exactly where an automated anti-virus system can help. It keeps a consistent watch on your system activities and blocks any malicious activity before it can cause a problem!

    This article is WELL out of date.

    ESET NOD32 Antivirus For Linux Desktop currently receives limited support, and will be terminated in the 3rd quarter in 2022.

    F-Prot were bought out by another company (Cyren) and is dead.

    Panda no longer appear to do anything involving Linux.

    The Comodo antivirus software can be downloaded, but is essentially useless due to requiring older libraries. I spent some time trying to get this to work, but no go. Others have done the same.

    Sophos was a fairly decent Linux based antivirus, however, they are also killing the free version of their Linux product.

    There are paid for Linux A/V software, however, most retail for around $250 per year for Business versions (like Avast), while not providing a home desktop version.

    This leaves us with ClamAV.

    ClamAV can be configured to use third party definitions, but testing this on a virtual install was so sluggish it wasn’t funny.

    Rootkit Hunter and Chkrootkit are still the main go to programs, but for the most part, Linux A/V is dead.
