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.

ClamAV 0.95 Engine End of Life Announcement

March 28th, 2014 Posted by -

ClamAV Community,

This notice is to inform you that effective immediately ClamAV 0.95 (and all minor versions) is no longer supported in accordance with ClamAV’s EOL policy which can be found here:

https://github.com/vrtadmin/clamav-faq/blob/master/faq/faq-eol.md

While the current CVD’s being distributed will still work on ClamAV 0.95, and we are not enabling the functionality to actually make those versions be able to update, this does serve as notice that we are no longer going to be testing against that version in our regression tests.

We will also be EOL’ing 0.96 in coming months, so if either of those versions is currently in use, it is highly suggested that you upgrade to the most current version.

Thank you for using ClamAV!

  1. Performance. OpenSSL has code optimized for many platforms. In several tests that we’ve performed, we’ve averaged (Read more...)
