Antivirus (Debian/Ubuntu/Xubuntu) Free

If you need an antivirus for Linux, which most users do not, then run the following command in Terminal Emulator.

sudo apt install clamav clamtk

How to do a full system scan with ClamTK. Note: It is unlikely that you will have viruses outside your home folder, as that would require root. Also, note that viruses are less common with Linux, when compared to other operating systems.

1. Open ClamTK.

How to scan the system with terminal emulator

Update database
$ sudo freshclam

Scan the whole system with information being displayed
$ clamscan -r -v --bell -i --exclude-dir="/sys" /

If you want to create a full system log (and have it save a text file with the results), you can run the following command. Note, this will scan the whole system (with no indication it is running besides your fans might ramp up, if you have any) and create a text file for viewing any infected files, if any are found.

$ clamscan -r -v --bell -i --exclude-dir="/sys" / > clamscan-results.txt

Another command you could run is …
$ clamscan -r / --log=scan_results.txt

Do not open the txt file before it is complete. I would open it in an advanced text editor like sublime (https://www.sublimetext.com/) and search for the word FOUND. This will show you which files it found. You may also run the following command below to have terminal show you any files it finds that are infected.

$ grep "FOUND" scan_results.txt

You can also use these commands:

This displays the txt after saving it.
$ sudo clamscan -r / --bell --exclude-dir="/sys" | tee clamscan-results.log

This command only shows anything it finds.
$ sudo clamscan -r / --bell --exclude-dir="/sys" | grep "found" > clamscan-results.txt
