What Is Adware? How It Works And How To Protect Yourself Against Adware

The adware (from the English term and used to refer to the software advertising) is a type of malware designed to display ads on the screen of any computer, usually for malicious purposes without our consent. Attacks any computer or device, of any brand, that has the possibility of installing applications: computers, mobiles, tablets, etc.

How Does An Adware Work?

Its mission is to collect our private information to create a user profile based on your preferences and thus be able to display advertisements based on the user’s interests. This type of malware can cause sensitive data stored on the device to end up in the hands of third parties without consent and without even knowing it.

Once the profile is done, when the user opens their web browser to access the Internet, the adware starts displaying ads on the screen randomly and at continuous intervals. Generally, the ads are displayed in full screen or in the form of notifications and can be so annoying that, sometimes, it will be quite difficult to get to use a computer, since notifications and windows open without stopping.

The objective of this adware is to earn income based on the number of clicks and downloads they receive, although lately there are also some variants that are already being used as malware campaigns to steal sensitive information from users (bank details, passwords, etc. ).

How Does It Reach Us?

Currently, this type of malicious software is resorting to stealth to infiltrate our computers without permission. Sometimes it pretends to be a legitimate program (eg, fake antivirus or antimalware ) and other times it accompanies a program in a hidden way (by downloading programs of type ‘freeware’ or ‘shareware’ that are usually free).

Not only with the download and subsequent installation can we have adware, but there are also websites of dubious reputation that take advantage of the lack of updates to our browser and system to self-install in a hidden way and without consent. Once the adware ‘hijacks’ the browser on our computer, it can analyze different parameters of our system, as well as the websites we visit and display advertisements according to our interests.

  • New toolbars, extensions or plugins have appeared in the browser.
