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

What kind of application is PublicSystem?

During examination of PublicSystem, it has been found that its main purpose is to show annoying advertisements. Apps that operate like PublicSystem are called adware. It is crucial to emphasize that users often unintentionally install applications like PublicSystem on their computers.

PublicSystem adware

PublicSystem adware in detail

The specific ads that an app like PublicSystem can display may vary, but generally, adware like this can show various types of intrusive advertisements, including pop-up ads, banners, full-screen ads, and in-text ads. Some of the ads presented by PublicSystem might redirect users to websites that host malware, phishing scams, or other security threats.

Also, users may be directed to deceptive websites that promote fake products, services, or offers. Moreover, clicking on ads shown by PublicSystem may trigger the download and installation of other unwanted software (e.g., browser hijackers). Thus, it is important to be cautious when encountering such ads and avoid clicking on them.

Furthermore, PublicSystem, like many adware applications, has the potential to collect user data. Adware often gathers information to tailor advertisements to users more effectively. This data may include browsing history, search queries, clicked links, IP addresses, and even personally identifiable information in some cases.

While the stated purpose of this data collection is typically for ad targeting, it can raise privacy concerns and pose a risk if the data is mishandled or shared with third parties without consent.

More about adware

Adware applications like PublicSystem can potentially hijack web browsers. They achieve this by altering browser settings without the user's consent. Common browser hijacking actions include changing the homepage, search engine, and new tab settings to redirect users to specific websites or display unwanted content.

More examples of apps similar to PublicSystem are PerfectSave, OverallHelpDesk, and PositiveConnectivity.

How did PublicSystem install on my computer?

Users often inadvertently install apps like PublicSystem through a process known as software bundling. This occurs when the adware is bundled with other software downloads from sources such as freeware or shareware websites. When users rush through the installation process and do not carefully review the options presented, they may unintentionally agree to install the bundled adware.

Additionally, some users may unknowingly install apps like PublicSystem by clicking on deceptive ads, downloading files from untrustworthy sources (e.g., P2P networks), or falling victim to misleading social engineering tactics.

How to avoid installation of unwanted applications?

Download software exclusively from reputable sources like official websites or trusted app stores, and steer clear of third-party download sites or stores. When installing software, review all prompts, choose custom or advanced installation settings, and deselect any unwanted applications.

Exercise caution by refraining from clicking on dubious ads and being vigilant when opening email attachments. Regularly inspect your system for unfamiliar or questionable software, and uninstall anything unfamiliar or untrusted. If your computer is already infected with PublicSystem, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
