WebShoppers Adware (Mac)

Also Known As: WebShoppers ads
Type: Mac Virus
Damage level: Medium

What is WebShoppers?

WebShoppers is a dubious application identical to CoolShopper, HotShoppy, EasyShopper, and several others. By falsely claiming to save time and money, WebShoppers often trick users to install. Although this application may seem legitimate, it is classed as a potentially unwanted program (PUP) and adware.

Be aware that this application often infiltrates computers without users’ permission. Furthermore, it collects various user/system information and delivers intrusive online advertisements.

WebShoppers adware

Following infiltration, WebShoppers records IP addresses, search queries entered into search engines, URLs visited, pages viewed, and other similar information relating to browsing activity. This collected data often contains personally identifiable details that are shared with third parties (who misuse private information to generate revenue).

Thus, data tracking can lead to serious privacy issues. Be aware that WebShoppers employs a 'virtual layer' to generate coupon, pop-up, banner, and other similar advertisements. None are derived from users' visited websites and often conceal underlying content, significantly diminishing the Internet browsing experience.

Clicking these ads is risky and might result in further computer infections, since some redirect to malicious websites. If WebShoppers has infiltrated your system without consent and you continually encounter third party advertisements, remove this application immediately.

Research shows that there are hundreds of adware-type applications sharing similarities with WebShoppers. All offer 'valuable features' to supposedly improve the Internet browsing experience, however, these apps are designed only to generate revenue for the developers - virtually none provide any real value for regular users.

Rather, applications such as WebShoppers deliver intrusive online advertisements (using the 'Pay Per Click' [PPC] advertising model), and continually gather various information (which is later sold to third parties).

How did WebShoppers install on my computer?

WebShoppers has an official download website and is also distributed using a deceptive software marketing method called 'bundling'.

Developers know that many users do not express enough caution when downloading and installing software and, thus, conceal bogus apps (including WebShoppers) within the 'Custom/Advanced' settings. By skipping this section, users expose their systems to risk of various infections and threaten their privacy.

How to avoid installation of potentially unwanted applications?

There are two simple steps you should take to prevent this situation. Firstly, never rush when downloading and installing software - select the 'Custom/Advanced' settings and analyze each step. Secondly, never accept offers to download/install third party applications and opt-out of those already included.
