How to remove SystemMonitor adware and the advertisements it delivers

Also Known As: Ads by SystemMonitor
Type: Adware
Damage level: Medium

What is SystemMonitor?

SystemMonitor is a rogue piece of software classified as adware. It operates by running intrusive advertisement campaigns and causing redirects to untrustworthy/malicious websites. Furthermore, it adds the "Managed by your organization" feature to Google Chrome browsers.

SystemMonitor collects browsing-related information, which is a serious privacy concern. This adware has been observed being distributed through deceptive installation set-ups (e.g., fake software "cracking" tools) and bundled with untrusted apps. These applications work in a similar way to SystemMonitor. Some have the capability to force-open browsers and cause redirects to bogus websites. Products proliferated using these dubious methods are classified as Potentially Unwanted Applications (PUAs).

SystemMonitor adware

Adware enables the placement of third-party graphical content (e.g., pop-ups, banners, coupons, surveys, full-page, and other intrusive ads), typically on any visited website. The delivered advertisements seriously diminish the browsing experience by limiting web page visibility and browsing speed.

Additionally, these ads are dubious, misleading, and even dangerous. Intrusive advertisements promote sale-based/promotional pages (of legitimate and bogus products), untrusted, rogue, compromised, deceptive/scam, and malicious sites.

Websites of this type can also be force-opened by SystemMonitor. Some intrusive ads can be triggered (when clicked) to execute scripts designed to download/install software (e.g., PUAs) without users' permission.

SystemMonitor has data tracking capabilities, which is typical of adware. Information of interest includes visited URLs, viewed pages, searched queries, IP addresses, geolocations, and even personally identifiable details. The collected data is monetized by sharing with and/or selling to third-parties (potentially, cyber criminals).

In summary, the presence of unwanted software on devices can lead to system infections, serious privacy issues, financial loss, and identity theft. To ensure device and user safety, all suspicious applications and browser extensions/plug-ins must be eliminated immediately upon detection.

AD&POP BlockWerise TweakerThe Rocket Arcade, and OneUpdater are some examples of software within the adware classification. It may seem legitimate and offer a broad range of "useful" functionalities, however, the promised features are seldom operational. In fact, this is true of most PUAs. The only goal of these unwanted applications is to generate profit for the developers.

PUAs operate by causing redirects, delivering intrusive ad campaigns, hijacking browsers, and collecting private data.

How did SystemMonitor install on my computer?

PUAs are distributed via download/installation set-ups of other products. This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling".

Rushing download/installation processes (e.g. ignoring terms, skipping steps and settings, etc.) increases the risk of inadvertently allowing bundled content into the system.

Some PUAs have "official" download sites. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs without users' consent.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation or purchase. All downloads must be done from official and verified sources, since dubious channels such as unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders commonly offer deceptive or bundled content.

When downloading/installing, read the terms, explore all possible options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, features, etc. Intrusive ads may seem normal and harmless, however, they can redirect to various dubious web pages (e.g. gambling, pornography, adult-dating, and many others).

If you encounter ads or redirects of this kind, inspect the system and remove any suspicious applications and browser extensions/plug-ins immediately.

If your computer is already infected with SystemMonitor, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
