How to remove SystemNotes adware from the operating system
Written by Tomas Meskauskas on (updated)
What is SystemNotes?
SystemNotes is software categorized as adware. As with most applications within this category, it is promoted as a tool for improving the browsing experience by providing fast searchers, accurate search results, etc. In fact, this rogue app diminishes the browsing experience by running intrusive advertisement campaigns.
Due to the dubious proliferation methods used to promote SystemNotes (most users download/install it inadvertently), it is also classified as a Potentially Unwanted Application (PUA). Furthermore, most PUAs (including adware) monitor users' browsing habits and gather information derived from it.
SystemNotes adware delivers a wide variety of annoying and harmful ads such as pop-ups, coupons, banners, surveys and so on. These seriously affect browsing, since they diminish browsing speed and limit website visibility (i.e., by overlaying page content), however, they are more than just a nuisance.
These ads are also a threat to device health and user safety. Once an intrusive ad is clicked, it can redirect to sale-based, untrusted, rogue, compromised, deceptive/scam and malicious web pages. Furthermore, these ads can be triggered (by clicking them) to execute scripts designed to stealthily download/install rogue software (e.g. PUAs).
These unwanted applications often have data tracking capabilities. They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect users' personal information (IP addresses, geolocations and other details).
It is highly likely that this sensitive data will then be shared with third parties (potentially, cyber criminals) intent on misusing it for profit. In summary, the presence of PUAs on systems can cause various infiltration and infections, lead to serious privacy issues, financial loss and even identity theft.
Therefore, to ensure device integrity and user safety, you are advised to remove all suspect applications and/or browser extensions/plug-ins immediately upon detection.

BenefitSites, ExpertModuleSearch and ActionHow are some examples of adware-type apps. They often appear legitimate and offer "useful" functions. The range of the features promised is broad, however, they are usually nonoperational. In fact, this applies to most PUAs whose only purpose is to generate revenue for the developers.
Rather than delivering any real value, PUAs deliver intrusive ad campaigns, force-open untrusted and malicious sites, modify browsers and restrict/deny access to settings, and track/collect private data.
How did SystemNotes install on my computer?
PUAs can be downloaded/installed together with other products. "Bundling" is the term used to define this deceptive marketing tactic of pre-packing normal software with unwanted or malicious additions. When downloading/installing, ignoring terms, using pre-set options, skipping steps and sections increases the risk of potential infiltration and infections via bundled content. Some PUAs have "official" promotional web pages from which they can be downloaded. These web pages are commonly promoted by deceptive/scam sites. Intrusive ads also proliferate these apps. Once clicked, they can execute scripts to download/install PUAs without users' permission.
How to avoid installation of potentially unwanted applications
You are advised to research all products to verify their legitimacy, prior to download/installation or purchase. Perform all downloads from official and verified sources.
Untrustworthy download channels such as free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders can offer deceptive or bundled content and should not be used.
When downloading/installing, read the terms, explore all possible options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, functions and so on. Intrusive ads typically seem legitimate and innocuous, however, they often generate redirects to dubious sites (e.g. gambling, adult-dating, pornography and others).
If you encounter these advertisements/redirects, inspect the system and remove all suspicious applications and browser extensions/plug-ins without delay. If your computer is already infected with SystemNotes, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
