adwareAdware is software that displays advertising on your browser. These programs are typically bundled with certain free software. Adware programs often create unwanted effects on a system and the general degradation in either network connection or system performance.

While not categorized as Malware, many users consider these popups and banners invasive. Adware is often installed in tandem with Spyware programs. Both programs feed off of each other’s functionalities – spyware programs profile users’ Internet behavior, while adware programs display targeted ads that correspond to the gathered user profile.

Adware does not directly spread in the manner of a computer virus or worm: generally, an infected system does not attempt to transmit the infection to other computers. Instead, the culprit is usually installed on a system when the user inadvertently agrees by accepting the End User License Agreement (EULA) on the free software.
