This definition explains the meaning of adware or advertising malware. Adware is relatively harmless compared with other types of malware, however, it is the most disruptive. It has the ability to:
- generate unwanted pop-up ads on sites you frequent,
- install additional toolbars on your browser, or
- change your browser’s homepage.
More malicious variations of adware, however, are designed to redirect users to malware-ridden websites. These variations are often bundled with free software which makes initial detection and removal especially difficult.
To avoid infection, read installation settings carefully and make sure no additional programs will be installed. If signs of adware do emerge, install and run adware-removal tools as quickly as possible.
