About ClamAV®


ClamAV is an open source (GPL) antivirus engine designed for detecting Trojans, viruses, malware and other malicious threats. It is the de facto standard for mail gateway scanning. It provides a high performance mutli-threaded scanning daemon, command line utilities for on demand file scanning, and an intelligent tool for automatic signature updates. The core ClamAV library provides numerous file format detection mechanisms, file unpacking support, archive support, and multiple signature languages for detecting threats. The core ClamAV library is utilized in Immunet 3.0, powered by ClamAV, which is a fast, fully featured Desktop AV solution for Windows.

You want to become a ClamAV mirror?

April 15th, 2013 Posted by -

One of the questions I receive in my inbox quite frequently is:

“Does ClamAV need any more mirrors for virus definitions?”

The quick answer is “Yes!”  We’ll always take more mirrors that we can get, as we increase output of virus definitions and such, we need more infrastructure to be able to handle the load.

If you are interested in becoming a ClamAV mirror, please follow the instructions here:

Resolving Issues With Freshclam

February 28th, 2013 Posted by - jesler

Certain users are experiencing database update issues due to the failed Authenticode database push. This blog post will show how to check if you’re one of those affected users and how to fix freshclam.


Validate You’re Affected

You can validate that you’re having this particular issue by a number of ways:

  1. Check the hash of your daily.cvd. You are affected if the hash matches the following:
    1. MD5: 89dedb45609e59b0244fb5202ab6fa56
    2. SHA1: 9947ec90e60499ab7c3331670d5b26b4eaac76e4

Planned Infrastructure Maintenance – 04 Mar 2013

February 25th, 2013 Posted by - jesler

In preparation for the ClamAV 0.98 release, we will be performing maintenance on the infrastructure beginning at 5:00 PM EST on 04 Mar 2013.

We will be pushing out a new signature database that does not have a corresponding cdiff file. This means that clients will pull down a full copy of the daily.cvd database, which will cause an increase in download traffic from the mirrors.

The maintenance is estimated to take one hour.  No impact to users, beyond the downloading of a new daily.cvd, is anticipated.

We would like to extend our thanks to the mirror providers for their contributions, and thank you for using ClamAV.
