Remove Nspchlpr and its associated files from Mac computers

What is "Nspchlpr"?

The pop-up message "nspchlpr will damage your computer. You should move it to the Bin." is associated with the Similar Photo Cleaner application. Nspchlpr files originate during the installation process of this rogue app. This is a more likely occurrence on devices with the Catalina version of the MacOS (Mac Operating System).

Immediate removal of all Nspchlpr-related files is strongly recommended. Helpermcp, Smbstrhlpr, and Helperamc are examples of other applications identical to Nspchlpr.

Nspchlpr files originate from the installation setup of the Similar Photo Cleaner app. This application is classified as a Potentially Unwanted Application (PUA) and it is likely that Nspchlpr is also one of these unwanted apps.

Furthermore, download/installation set-ups used to proliferate this software often contain more than one PUA (e.g. adware or browser hijackers). PUAs have various harmful capabilities.

They can cause redirects to sale-oriented, untrustworthy, compromised and malicious websites, deliver advertisement campaigns (pop-ups, banners, surveys, coupons, etc.), and some can track private data. Associated risks include browser and system infiltration/infections, severe privacy issues, financial loss, and even identity theft.

Due to these threats, Nspchlpr and Similar Photo Cleaner must be removed without delay. All suspicious applications and browser extensions/plug-ins must be removed immediately to ensure device and user safety. The steps required to remove Nspchlpr and its associated files are listed below. Prior to removal, Nspchlpr should be terminated using Activity Monitor.

PUAs proliferate in dubious ways and/or trick users into installation. They often seem legitimate and offer "useful" and "beneficial" features, however, these features rarely operate as advertised and, in most cases, are nonoperational. The only purpose of unwanted software/content is to generate revenue for the developers, whilst regular users receive no value.

Advanced Mac Cleaner, Mac Cleanup Pro, and Smart Mac Booster are just some examples of PUAs similar to Similar Photo Cleaner.

How did potentially unwanted applications install on my computer?

PUAs can be installed by users without their consent. Some unwanted applications have "official" download websites on which they are endorsed as "free" and "useful" software. They also proliferate via the download/installation set-ups of other programs. The deceptive method of pre-packing regular software with unwanted or malicious content is called "bundling".

This technique is widely used by PUA developers and is often successful in proliferating their products. Rushing download/installation processes (e.g. ignoring terms, skipping steps, using pre-set options, etc.) increases the risk of potential system infiltration and infections.

Intrusive advertisements are also known to proliferate PUAs. Once clicked, they execute scripts to download/install unwanted applications without users' permission.

How to avoid installation of potentially unwanted applications

You are strongly advised to research content (files, apps, tools, features, etc.) to verify its legitimacy before downloading/installing. Only official and verified download sources should be used.

Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), free file-hosting and unofficial websites, third party downloaders and similar channels are classed as dubious and untrustworthy and, therefore, should not be used. These sources are more likely to offer unwanted/malicious software or bundled content.

Download and installation processed should be treated with caution. Read the terms, explore all possible options, use the "Custom/Advanced" settings, and opt-out of downloading/installing additional content.

Intrusive ads are commonly hosted by compromised sites and often seem legitimate and harmless, however, when clicked, they can redirect to rogue web pages (e.g. gambling, pornography, adult-dating, etc.).

If you experience ads/redirects of this type, inspect the system for suspicious applications and/or browser extensions/plug-ins and remove them immediately to ensure device integrity and user safety. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
