NoterSave Adware
Written by Tomas Meskauskas on (updated)
What is NoterSave?
NoterSave is a rogue application that supposedly allows users to create and organize various notes. Initially, this functionality may seem legitimate and useful, however, this app is categorized as a potentially unwanted program (PUP) and adware.
The main reasons for these negative associations are: 1) stealth installation without consent; 2) tracking of users' Internet browsing activity, and; 3) display of intrusive online advertisements.
Following infiltration, NoterSave monitors browsing activity by gathering various data including Internet Protocol (IP) addresses, website URLs visited, and queries entered into search engines - these are just some examples from many gathered data types. This behavior is very common to adware-type applications. Bear in mind that the data might be personally identifiable.
Developers generate revenue by selling it to third parties (potentially, cyber criminals) who also aim to increase their revenue by misusing users' personal details. This might cause serious privacy issues. Furthermore, NoterSave delivers intrusive online advertisements. PUP developers use a "virtual layer" - a tool that enables placement of third party graphical content on any site.
Therefore, pop-ups, coupons, banners, and other displayed ads often conceal underlying content, significantly diminishing the browsing experience.
These ads can lead to malicious websites or even execute scripts that download and install malware. Therefore, even accidental clicks can result in high-risk adware or malware infections. For these reasons, we strongly advise you to uninstall NoterSave adware immediately.

NoterSave has very similar characteristics to Always Weather, Search In Tabs, Fooriza, ShutDownTime, and dozens of other adware-type applications. Note that all offer different functionality, but have identical behavior. Claims to provide 'useful features' are merely attempts to give the impression of legitimacy.
NoterSave, and other similar adware, is designed only to generate revenue for the developers. These apps merely deliver intrusive online advertisements (via the "Pay Per Click" advertising model) and continually record various user-system information (which is later sold to third parties).
How did NoterSave install on my computer?
This PUP has an official promotion website, however, criminals also proliferate these rogue programs by employing a deceptive marketing method called "bundling" - stealth installation of third party programs with regular software/apps. Therefore, PUPs often infiltrate systems without permission (or users install them inadvertently).
Bundled applications are hidden within the "Custom/Advanced" options of the download or installation processes.
As mentioned above, PUPs (malware) are also distributed using intrusive online advertisements. Therefore, rushing the download/installation processes, skipping steps, and clicking various advertisements, exposes systems to risk of various infections and compromises users' privacy.
How to avoid installation of potentially unwanted applications?
Poor knowledge and careless behavior are the main reasons for computer infections. PUPs are distributed using intrusive advertisements and the aforementioned bundling method. Avoid clicking intrusive advertisements, since cyber criminals do their best to make them appear legitimate.
It is virtually impossible to determine if displayed ads originate from visited websites - do not take the risk by clicking them.
It is also important to download applications from official sources only and select the direct download URL, rather than using third party tools. In addition, carefully study the download/installation processes using the "Custom/Advanced" settings and cancel all additionally-included programs. The key to computer safety is caution.
