Adware, malware, spyware, software, what helps your computer and what isn’t so beneficial to your system? It can be difficult to tell, and this is especially true of adware. Adware itself isn’t harmful on its own, and it isn’t always used in malicious applications. While adware can be a close relative of spyware, it can also be used legitimately by reputable programs. How can you tell the difference between real and rogue applications?
What is Adware?
Adware is ad-supported software. Unlike freeware, which allows you to download and use the program free, adware comes with a caveat: if you want to use, you must allow the ads that support the program. The Eudora email client, for instance, is a form of adware in the sense that it is advertising-supported software. But many times, adware is a form of spyware. The difference is that the user gives consent for the legitimate adware program to install, while spyware installs itself surreptitiously. The objective of adware is to track and record your browsing habits in order to sell this data to advertisers for “targeted” advertising.
How Does Adware Enter a System?
You elect to install legitimate adware; you will see a user agreement and/or end-user license agreement, and it is in these terms of use that you are agreeing to display the ads. A legitimate adware program displays these unobtrusively, and you have the option to use the Remove function. In contrast, adware installs without your knowledge and displays nuisance pop-ups. How does adware enter your system?
