CompariShop Adware (Mac)

Also Known As: Ads by CompariShop
Type: Mac Virus
Damage level: Medium

What is CompariShop?

CompariShop is a rogue application identical to LiveShoppers, ShoppyTool, MyCouponize, and many others. By offering functionality to save time and money (coupons, notifications about special deals/discounts on various online shops, etc.), CompariShop attempts to give the impression of legitimacy.

Be aware, however, that this app is categorized as adware and a potentially unwanted program (PUP). There are three reasons for these negative associations: 1) display of 'malvertising' ads; 2) information tracking, and; 3) stealth installation without users' consent.

CompariShop adware

Immediately after installation, CompariShop delivers coupons, banners, pop-ups, and other intrusive ads. These are displayed using tools that enable placement of third party graphical content on any site. The ads often conceal underlying content of visited websites, significantly diminishing the browsing experience.

Furthermore, some redirect to various websites and/or run scripts that download/install malware or other PUPs. Therefore, even accidental clicks can result in high-risk adware or malware infections. This program is essentially used to generate 'malvertising' revenue.

As mentioned above, CompariShop also records sensitive data. Internet Protocol (IP) addresses, keystrokes, website URLs visited, pages viewed, queries entered into search engines, and other collected data, is later sold to third parties (potentially, cyber criminals). Thus, the presence of an information-tracking app can lead to serious privacy issues or even identity theft.

Potentially unwanted programs often misuse system resources to run unwanted processes (e.g., to mine cryptocurrency) without users' consent. This behavior results in a significant reduction in overall system performance. For these reasons, apps such as CompariShop should be eliminated immediately.

All adware-type programs are very similar. By offering various useful features (e.g., system performance optimization, download performance increase, anti-virus, etc.), PUPs aim to trick users to install. In fact, only a small percentage of adware-type apps give any real value for regular users - most are useless.

In fact, they are designed only to generate revenue for the developers (via the "Pay Per Click" [PPC] advertising model, information sale, mining cryptocurrency, etc.) Therefore, rather than (or, in some cases, together with) enabling the functions promised, potentially unwanted programs pose a direct threat to your privacy and Internet browsing safety.

How did CompariShop install on my computer?

This adware has an official download website, however, as with most other PUPs, CompariShop is also distributed using 'malvertising' ads and a deceptive marketing method called "bundling" (stealth installation of third party software together with regular apps).

Therefore, due to careless behavior by many users and lack of knowledge, CompariShop infiltrates systems without permission. Developers do not properly disclose installation of "bundled" software - they conceal such information within the "Custom/Advanced" settings or other sections of the download/installation processes.

Rushing these processes, skipping steps, and clicking ads, often leads to inadvertent installation of potentially unwanted programs thus exposing the system to risk of various infections and compromising your privacy.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution. Pay close attention when downloading/installing software and browsing the Internet in general. As mentioned above, PUPs are distributed using the "bundling" method.

Therefore, carefully analyze each window (especially the "Custom/Advanced" settings) of the download/installation dialogues and cancel all additionally-included programs. "Bundling" is also used to monetize third party download/installation tools (they promote malicious apps). Therefore, these tools should never be used.

Note that criminals invest a great deal of resources into malicious ad design. Therefore, these ads usually appear legitimate - determining if they originate from the visited (legitimate) website is difficult.

In fact, these ads are notable since they redirect to survey, gambling, adult dating, pornography, and other rogue websites. If you are redirected to such websites, uninstall all suspicious applications and browser plug-ins.
