These are the programs that deliver unwanted ads to your computer (generally in Pop-Ups form). They consume your network bandwidth. Adware is similar to spyware—however, it may be installed with your consent. So it is advised that you thoroughly read installation agreements before you allow installation of a software.
DAMAGE CAUSED BY ADWARE
Adware comes complete with the following disadvantages:
》Adware tracks information just like spyware. Adware tracks information about your data and computing habits to produce targeted advertising, such as pop-up ads, on your computer screen.
》Displays arrays of annoying advertising. When infected with adware, you will likely see frequent pop-up ads appear out of nowhere. This may even happen every time you open your web browser.
》Slows down your PC. The adware software working in the background and the bombardment of ads can slow your PC to a crawl.
