ClamAV is an open source antivirus engine developed by Sourcefire, and Sourcefire is also the owner of the Snort intrusion detection engine. ClamAV provides a faster and more flexible framework for detecting malicious code and software products. It can be used as a supplementary tool or alternative to existing desktops, file servers, mail servers and other antivirus scanning software scenarios that require antivirus scanning software. In addition, the ClamAV package also contains libclamav library and command line executable file interface. At the same time, a freshclam command line tool is provided to ensure the update of the feature library.

Clam AntiVirus (ClamAV) is free and open source antivirus software, software and virus code updates are released free of charge by the community. At present, ClamAV is mainly used on mail servers set up by Linux, FreeBSD and other Unix-like systems to provide e-mail virus scanning services. ClamAV itself operates under the text interface, but there are also many front-end tools for the graphical interface available. In addition, because of its open source characteristics, there are portable versions in both Windows and Mac OS X platforms.

Here's a look at the installation of ClamAV on CentOS:

1. Go to http://pkgs.repoforge.org/clamav/ and install the package now

The code is as follows:

Wget http://pkgs.repoforge.org/clamav/clamav-db-0.98.4-1.el6.rf.x86_64.rpm

Wget http://pkgs.repoforge.org/clamav/clamav-0.98.4-1.el6.rf.x86_64.rpm

Wget http://pkgs.repoforge.org/clamav/clamd-0.98.4-1.el6.rf.x86_64.rpm

2. Installation

The code is as follows:

Rpm-ivh clamav-db-0.98-2.el6.rf.x86_64.rpm

Rpm-ivh clamav-0.98-2.el6.rf.x86_64.rpm

Rpm-ivh clamd-0.98-2.el6.rf.x86_64.rpm

3. Start the service

The code is as follows:

Service clamd start

4. Update the virus database

The code is as follows:

Freshclam

5. Scanning

Scan a directory

The code is as follows:

Clamscan-r / home/oicqzone

Store the scan results in log

The code is as follows:

Clamscan-r / home/oicqzone-l / tmp/clamav.log

During the scan, only the problematic files are displayed and the alarm sound is made.

The code is as follows:

Clamscan-r-bell-I / home/oicqzone

Scan the file in question and delete it directly.

The code is as follows:

Clamscan-r-remove / home/oicqzone

Be careful in this step, it is best not to do this, and carefully delete the system files and cause the system to crash

When clamAV has scanned all the files, a report similar to the following is displayed

-SCAN SUMMARY-

Known viruses: 33840

Scanned directories: 145

Scanned files: 226

Infected files: 1

Data scanned: 54.22 MB

I/O buffer size: 131072 bytes

Time: 20.831 sec (0 m 20 s)

ClamAV only scans files that can be read by ClamAV. If you want to scan all files, add sudo before the command.

Make ClamAV run in daemon protected mode

Just install clamav-daemon. Clamav-daemon will set up an account called 'clamav', so that ClamAV can scan some system files, such as where your Email is stored, and you can add' clamav' as the owner of these files or directories.

How to know more parameters

Use

The code is as follows:

Man clamscan.

How to make ClamAV run automatically as scheduled

You can use the 'at' command to make clamscan and freshclam run, such as

The code is as follows:

At 3:30 tomorrow

At > clamscan-I / home/user > mail user@example.com

At >

Job 3 at 2005-04-28 03:30

Or edit / etc/crontab to add the following
