How to remove Internet Security Damaged from Mac?

What is Internet Security Damaged?

"Internet Security Damaged" is a fake error message displayed by a rogue website that is often visited by users inadvertently - they are redirected by various potentially unwanted programs (PUPs). These applications infiltrate systems during installation of other software (the "bundling" method). As well as causing unwanted redirects, PUPs deliver intrusive online advertisements and continually monitor users' Internet browsing activity.

Note that "Internet Security Damaged" targets Mac OS user only. This error message states that a suspicious connection has been detected and, for this reason, the Internet connection has been blocked. In addition, personal information (logins and passwords, banking details, etc.) may be leaked. Therefore, the problem must be resolved immediately. To do so, victims are encouraged to contact 'certified technicians' via a toll-free telephone number ("+1-800-576-7509") provided. In fact, "Internet Security Damaged" is fake. Cyber criminals attempt to scare victims and trick them into calling and paying for services that are not required. This pop-up is not genuine and should not be trusted. You can remove "Internet Security Damaged" simply by closing the web browser. Furthermore, PUPs employ a "virtual layer" to generate pop-up, coupon, banner, and other similar ads. The virtual layer is a tool that enables placement of third party graphical content on any site. Therefore, displayed ads often conceal underlying website content. This significantly diminishes the web browsing experience. In addition, these ads might redirect to malicious websites - even accidental clicks can result in high-risk adware or malware infections. Furthermore, potentially unwanted programs continually record information relating to Internet browsing activity. The collected data (IP addresses, URLs visited, pages viewed, etc.) might contain personal details that PUP developers share with third parties. These people (often cyber criminals) generate revenue by misusing personal information. Thus, information tracking can lead to serious privacy issues or even identity theft. We strongly recommend that you uninstall all potentially unwanted programs immediately.

"Internet Security Damaged" shares many similarities with dozens of other fake error messages such as Apple Security Damaged, Immediately Call Apple Support, Your Device Has Been Blocked, and many others. All claim that the computer is infected or damaged in other similar ways, however, all these statements are false. As mentioned above, fake errors are designed to scare victims and trick them into paying for services that are not required. Potentially unwanted programs are designed only to generate revenue for the developers. By offering various 'useful features', they attempt to give the impression of legitimacy, however, these applications merely cause unwanted redirects, deliver intrusive advertisements, and gather various user/system information. PUPs are useless for regular users.

How did Internet Security Damaged install on my computer?

As mentioned above, PUPs are distributed using the "bundling" method - stealth installation of third party applications with regular software. These programs are hidden within the "Custom/Advanced" settings of the download or installation processes. Rushing these procedures and skipping steps exposes the system to risk of various infections and compromises users' privacy.

How to avoid installation of potentially unwanted applications?

To prevent system infiltration by PUPs, be very cautious when downloading and installing software. Select the "Custom/Advanced" settings and closely analyze each step. Furthermore, decline offers to download/install additional applications and cancel those already included. The key to computer safety is caution.

Virus Info:
A Trojan horse, or Trojan, in computing is a non-self-replicating type of malware program containing malicious code that, when executed, carries out actions determined by the nature of the Trojan, typically causing loss or theft of data, and possible system harm. The term is derived from the story of the wooden horse used to trick defenders of Troy into taking concealed warriors into their city in ancient Greece, because computer Trojans often employ a form of social engineering, presenting themselves as routine, useful, or interesting in order to persuade victims to install them on their computers.
A Trojan often acts as a backdoor, contacting a controller which can then have unauthorized access to the affected computer. The Trojan and backdoors are not themselves easily detectable, but if they carry out significant computing or communications activity may cause the computer to run noticeably slowly. Malicious programs are classified as Trojans if they do not attempt to inject themselves into other files (computer virus) or otherwise propagate themselves (worm).
A computer may host a Trojan via a malicious program a user is duped into executing files or browsing internet.
