It’s Spring Time and after a long Winter surfing the web and testing new programs, it’s time to give a short rest to your computer, delete old files and scan the OS looking for possible rootkits or viruses. I usually use Ubuntu and the possibility of viruses is not high but… why I shouldn’t double-check to avoid viruses or rootkits?
- First step: Rootkits
Open your favourite Software Manager (I am na old school boy so Synaptics it’s my choice) and install rkhunter and chkrootkit. I know, they are two different programs that have the same goals so you can decide to install and use just one of them…
After the installation you can start using them just typing into a Terminal:
sudo rkhunter --update sudo rkhunter --check
Examine all the results and don’t be disoriented by possible “”false positives”. Try to understand if some “risks” you find in the results logs could be regular software you are using (e.g. encrypted disks, etc..)
- Second Step: Viruses
Install ClamAV to scan your disks and be sure you have not infected by common viruses.
Open a Terminal and type:
sudo aptitude install clamav clamav-daemon clamav-freshclam clamtk
Then to update the ClamAV engine and the virus lists just type:
sudo apt-get upgrade clamav clamav-daemon clamav-freshclam clamtk
At this point you find ClamTk into the Accessories Menu and you are able to scan your PC just clicking on some intuitive buttons in the graphical interface.
