Updating clam antivirus in ubuntu
Clam AV has official support in Ubuntu for packages installed from the Main repository. In case you are recursively scanning the whole /home folder (or even the whole system) from a terminal emulator on your GUI, possibly there will be lots of files.
The application was developed for Unix and has third party versions available for AIX, BSD, HP-UX, Linux, OS X, Open VMS, OSF (Tru64) and Solaris.For Clam AV to work properly, both the Clam AV engine and the Clam AV Virus Database (CVD) must be kept up to date.Freshclam should perform these updates automatically. Instructions for setting up Freshclam can be found in the Clam AV Manual or in the documentation section.There aren't many viruses made for Linux distributions and as such, most people who use such systems don't ever bother using an antivirus software.Those however who do want to be able to scan their system or other windows-based systems that are connected on a Linux PC through a network, they can use Clam AV.Clam AV is an open source anti-virus engine that is built to detect viruses, trojans, malware and other threats.
It supports multiple file formats (documents, executables or archives), utilizes multi-thread scanner features and receives updates for its signature database at least 3-4 times a day.freshclam Now we are ready to scan our system. This is a rich command that can work with many different parameters so you'd better insert “clamscan –-help” on the terminal first and see the various things that what you can do with it.
In that case you can do the following: Be patient if you run that command and it doesn't seem to be working because even if you don't see the complete output it is really scanning the files.
When you see the prompt again, that will mean the scan is finished and that you can open the file it has created to check any infected file detected in your system.
There are two classes of clamav packages available for Ubuntu users: The released set (release, *-updates, and *-security) are patched for security updates.
Following extensive testing of clamav and the packages that use it in the backports repository, they may be updated to a newer version.
Clam AV has two modes of operation; a program that loads into memory only when you want to scan a file, or for more regular use (such as scanning all incoming e-mail), a program that connects to a daemon that is always running.
