Although originally developed for Unix, it is now available in AIX, BSD, HP-UX, Linux, macOS, OpenVMS, OSF, and Solaris versions. The application supports a wide range of file formats, including mail formats, archive formats, executables, and popular document formats. Basically, the package consists of an anti-virus engine, which can be accessed as a shared library.

 

 

Let’s begin the installation process,

 

 

First, For Ubuntu system to be registered on the VPSie platform, A VPSie account needs to be created if it hasn’t been created already.

 

 

Our example is based on an Ubuntu instance with GUI installed. Here is a link that will guide you to installing Ubuntu’s GUI if you do not already have it installed.

 

Now open your terminal and run the following commands to update your system.

 

# apt-get update && apt-get upgrade -y

Let’s get to the installation, run the following command to install ClamAV

 

# sudo apt-get install clamav

 

Step 2: Install ClamAV Daemon

 

Run the following command to install it:

 

 

# sudo apt-get install clamav-daemon

 

 

Now let’s update the clamAV, you will see some errors please ignore it, it will auto-update anyway.

Step 3: Scan using CalmAV

 

 

ClamAV is now ready for use. Here you can use many scanning commands. Let’s take a look at a few of them now. For example we will scan the root directory.

 

Run the following command to scan the home directory:

 

# clamscan -r /root

 

 

Run the following command to see the infected items in your home directory.

 

# clamscan -ri /root

 

In order to remove the infected file, you can use the following command. However, this command is not recommended as it will destroy your files if it is infected. If you wish to delete files, use this command.

 

# clamscan -ri --remove /root# clamscan -r --move=/root/VIRUS /root

 

For avoid complications when deleting files. It is possible to create a folder and move the infected files inside it. Hence, you can check which files need to be removed and remove them accordingly. Run the following command to do so.

 

Run the following commands :

 

# mkdir VIRUS - Create Folder
# ls  - To check the folder created or not
# cd VIRUS/ - To navigate in to the folder
# pwd  - To copy the location of file.

 

Then, run the command to move the infected file to the folder we just created. On the command /root is the folder we are going to scan.

 

# clamscan -r --move=/root/VIRUS /root

 

 

Once the scanning is complete, you can check the folder and delete files if necessary.

 

Step 3: Install CalmAV UI
