About this interactive

The Software Distribution Methods lesson and the Acrobat Reader demo make the same three checks every time software is downloaded. The source. Go straight to the official source: the maker of the software or of the device, like Dell for a Dell laptop's driver or adobe.com for Acrobat Reader, or a store like the Microsoft Store. Skip the sponsored results at the top of a search, and be careful with third-party download sites, above all for drivers and operating systems. The extras. Download pages and installers often come with a box already ticked: install McAfee Security Scan Plus, send usage data, add a toolbar. Read every box and untick what you did not come for. A box for something you do want, like making Acrobat your default PDF app, is fine. The fingerprint. Legitimate software is code signed: when you run the installer, User Account Control shows the verified publisher, Google LLC for Chrome, Adobe for Acrobat Reader. Linux downloads usually come with a hash to compare with your copy's. A publisher you did not expect, an unknown publisher, or a hash that does not match means this is not the copy the maker released: get it again from the official source. Drag each card into a bin, then check your answers.
