I don&#x27;t, and I don&#x27;t.  On the other hand, I do know what I am clicking on, and I don&#x27;t execute a program I have not explicitly trusted.  (Mostly.  The OS itself trusts many programs, which trust programs…)<p>When I download stuff from the Debian repository, I trust the Debian team to do the security scanning for me.  When I download The Witness, I trust Jonathan Blow, his team, and the distribution channel not to put malware in there.  When I download a crack for some game I might or might not have bough, I trust the popularity of the corresponding torrent to correlate with a lack of malware.<p>And when a pop-up bugs me, I just close it.<p>I won&#x27;t deny my computer is at risk.  It is.  Unlike most people however, I can use Windows for 2 years and have almost zero malware on it.  Many people on the other hand let enough malware in to lag their computer to a crawl after a few months.<p>Education doesn&#x27;t solve all problems, but it does solve many —maybe even most.
