In the context of peer – mentoring, a presentation was made by a student to his fellow students, at the Second Chance School of Mytilene. Theodore Boumas talked about the best programmes for the protection of our computers from viruses and other malicious software. He also presented programmes that help computers run faster by cleaning files, extracting cookies etc. The presentation had both a theoretical and a practical level since Theodore showed us on the spot how to load, install and run certain programmes on the PC. The presentation was well received and Theodore promised to come up again with a new topic on the use of computer technology.
