What is Adware?

Adware is described as advertising-supported software programs that are designed to deliver variety of advertisements upon the web browsers.

Not all ad-supported programs are malicious. It is actually a method of advertising to gain user’s attention and promote affiliate products by delivering various advertising methods. For this, the Adware program tracks the browsing habits of users to display relevant ads to their browser while surfing. Thus, gaining traffic to their promotional websites and boosting sales process.

But many cyber offenders or group of people managing suspicious program deploy them to the web browser to flood the whole browser with an innumerable quantity of ads, pop-ups, linked videos, in-text links, banners and other forms of commercials to make profits from user’s pay-per-click method.

These ads when knowingly or unknowingly clicked by the user redirects to third-party websites or any other malicious web page that could be risky.

Adware has the main purpose to make profits either by pay-per-click or redirecting users to suspicious websites that may drop other illegitimate or malicious programs to the concerned devices. Some Adware is even programmed to silently collect user’s browsing-related information and monetary information like bank account logins, credit card numbers and so on. Such activities, later on, may lead to frauds.

If your browser is infected with any Adware then, you may encounter these symptoms:

  • Lots of ads and pop-ups appear frequently on your browser;
  • Browser redirects to anonymous web pages showing irrelevant contents;
  • Unknown browser extensions, add-ons, and toolbars added;
  • Web pages take too much time to load and often crash down.
  • Redirect pop-ups asking to install any extension/flash player or updated browser version.

Sometimes Adware often affects the system performance as they install other potentially unwanted programs to it.

The presence of an Adware program for too long within a system can even lower the security of the attacked system and create security flaws due to which other harmful threats could also attack the vulnerable computer system.
