The joke is that Windows doesn&#x27;t do self-cleaning like the Mac does and Windows machines often come installed with bloatware that is frequently harmful to the correct functioning of a personal computer.<p>Also Macs don&#x27;t get viruses as frequently. I&#x27;m not saying they&#x27;re less susceptible but it does happen less often.<p>(see: any recent COTS Windows PC, especially Lenovo)
