Uma das atividades prediletas dos leitores deste CL&M é fazer download dos livros, artigos e CDs indicados. No entanto, precisamos estar sempre de orelha em pé com relação ao download desavisado de virus, que têm em arquivos executáveis sua principal plataforma de lançamento (para dentro do nosso HD). Dos arquivos executáveis, os mais conhecidos são aqueles com extensão .exe, mas existem muitos outros que devem ser evitados com a mesma diligência (não sendo de fonte totalmente confiável).
