/sysé o ponto de montagem de um sistema de arquivos virtual sysfs :

O sysfs é um sistema de arquivos virtual fornecido pelo kernel do Linux. Usando arquivos virtuais, o sysfs exporta informações sobre vários subsistemas do kernel, dispositivos de hardware e drivers de dispositivo associados do modelo de dispositivo do kernel para o espaço do usuário. Além de fornecer informações sobre vários dispositivos e subsistemas de kernel, os arquivos virtuais exportados também são usados ​​para sua configuração.

Os arquivos /sysnão são arquivos reais; os vírus não os infectam. Além disso, você não pode criar novos arquivos /sys, tente você mesmo! Não há necessidade de digitalizá-lo. Use a opção de linha de comando --exclude-dir="^/sys"para ignorar /sys.
