SystemMonitor adware removal instructions

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 severe privacy concern. This adware has been observed being distributed through deceptive installation setups (e.g., fake software "cracking" tools), bundled together with untrustworthy apps. It is noteworthy that these applications work similarly to SystemMonitor. Some have the ability to force-open browsers and cause redirects to dubious sites. Products proliferated using such questionable methods are considered to be PUAs (Potentially Unwanted Applications).

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 cripple the browsing experience by limiting webpage visibility and browsing speed. Additionally, these adverts are unreliable, misleading, and even dangerous. Intrusive advertisements promote sale-based/promotional pages (of legitimate and illegitimate products), untrustworthy, rogue, compromised, deceptive/scam, and malicious sites. Websites of this type can also be force-opened by SystemMonitor. Some intrusive ads can be triggered (by being clicked on) to execute scripts designed to download/install software (e.g., PUAs) without user permission.

SystemMonitor has data tracking abilities, 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 being shared with and/or sold to third-parties (potentially, cyber criminals). In summary, presence of unwanted software on devices can lead to system infections, serious privacy issues, financial losses, 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 tends to appear legitimate and offers a broad range of "useful" functionalities. However, the promised features are seldom operational. In fact, this is true of practically all PUAs. The only goal of unwanted applications is to generate profit for the developers; hence, functionality and user privacy are irrelevant. PUAs operate by causing redirects, delivering intrusive advert campaigns, hijacking browsers, and collecting private data.

How did SystemMonitor install on my computer?

PUAs are distributed via download/installation setups of other products. This deceptive marketing tactic of pre-packing regular software with unwanted or malicious additions - is termed "bundling". Rushed download/installation processes (e.g., ignored terms, skipped steps and sections, etc.) increase the risk of unintentionally allowing bundled content into the system. Intrusive advertisements spread PUAs as well. Once clicked on, the ads can execute scripts to make stealthy downloads/installations. These applications may also have "official" promotional/download webpages.

How to avoid installation of potentially unwanted applications?

It is recommended to research software before download/installation and/or purchase. Additionally, all downloads must be done from official and verified sources. Untrustworthy download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer harmful and/or bundled content. When downloading/installing, it is advised to read terms, explore possible options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features, etc. It is just as important to exercise caution when browsing. Intrusive adverts appear ordinary and harmless; however, they redirect to various unreliable and questionable sites (e.g., gambling, pornography, adult-dating, and so on). In case of encounters with ads and/or redirects of this kind, the system must be checked and all suspect applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with SystemMonitor, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this adware.
