WHAT IS ADWARE? HOW IT WORKS AND HOW TO PROTECT YOURSELF AGAINST ADWARE



WHAT IS ADWARE?
Adware, or advertising-supported software, displays advertisements to a user when they are online in order to generate revenue for their author. It is a source of revenue for free service providers, and is not inherently malicious, though it has often become synonymous with advertisements. Non-malicious adware collects data with your consent. For example, you may consent to download the free version of an application that serves ads versus the paid ad-free version of the application. Companies that depend on adware to support their products or services include Google, Facebook, Skype, and Spotify.
HOW DOES ADWARE WORK?
When a company chooses to use adware to support its software, the adware is bundled or integrated with the program itself. This allows for advertisements to load automatically. Ad space is bought by other companies who want to market to the users of that program, and the revenue made by selling ad space may be used to cover user and/or development costs. Some companies integrate adware with their program in such a way that the program cannot run unless the ads are being displayed. Any ad blockers must then be disabled in order to use the software. Adware also often collects personal information and tracks users’ browsing habits, which is then sold to third parties.

How to Turn Wi-Fi On or Off With a Keyboard or Desktop Shortcut in Windows

Image
Some laptops come with “Wi-Fi” function keys or switches that can quickly enable or disable your Wi-Fi. If your PC doesn’t have one of these, though, you can make one with the tools built into Windows. You’ll need to start by creating a desktop or start menu shortcut. Once you’ve done that, you can invoke it with a keyboard shortcut, if you like. Step One: Find the Name of Your Wi-Fi Connection First, you’ll need to check the name of your Wi-Fi connection. You’ll need this to write the commands that enable and disable the Wi-Fi connection. Head to Control Panel > Network and Internet > Network and Sharing Center > Change Adapter Settings. Note the name of the Wi-Fi connection you want to disable. In the screenshot below, the name of the connection is “Wi-Fi”. Step Two: Create the Desktop Shortcuts Now that you know the name of the connection, you can create the desktop shortcuts you need. Right-click the Windows desktop and select New > Shortcut to creat
