How to remove Helpermcp from Mac?

What is Helpermcp?

The number of MacOS users who get a pop-up message "helpermcp will damage your computer you should move it to bin." is increasing by the day. Research shows that this pop-up appears mostly on the newest MacOS version called Catalina. It is known that Helpermcp is associated with an unwanted application called Mac Cleanup Pro. To be more precise, Helpermcp files originate during installation process of Mac Cleanup Pro. We strongly recommend to uninstall Mac Cleanup Pro and remove all files that are associated with Helpermcp as soon as possible.

Helpermcp pop-up virus

As we mentioned in the introduction, files related to Helpermcp originate through installation setup of Mac Cleanup Pro. Mac Cleanup Pro is a potentially unwanted application (PUA) that should not be trusted. Additionally, there are many cases where setups of such app are used to distribute other unwanted applications, for example, adware. It is very likely that Helpermcp is one of these apps. Having them installed on MacOS might lead to unwanted downloads, installations, redirects to shady pages, and other problems. Either way, it is not safe to keep Helpermcp or Mac Cleanup Pro installed. Besides, it is known that Mac Cleanup Pro is distributed through various deceptive pages. It means that people often download and install apps of this type because they are being tricked into it. To eliminate unwanted applications and files related to Helpermcp we recommend to scan system with a reputable antivirus software like Combo Cleaner. The list of files that should be removed from the system is provided below. Before removing them we recommend to terminate the "helpermcp" using Activity Monitor.

In most cases various unwanted apps are advertised as tools that are useful in one or another way. However, usually they do not operate as they supposed to. More often than not they cause only problems. Besides, very often they are distributed through questionable, deceptive websites. Apps of this type should not be downloaded or installed, if any app of this type is already installed, it should be removed as soon as possible. Examples of apps that are distributed through shady pages and similar to Mac Cleanup Pro are: Advanced Mac Booster, Speedup Mac Pro and Smart Mac Tuneup.

How did potentially unwanted applications install on my computer?

Most people download and install various unwanted, potentially malicious apps unwillingly/unintentionally. They cause it by clicking deceptive advertisements or by inappropriately downloading and/or installing various software. Typically, to trick users into unintentional downloads or installations developers use a deceptive marketing method called "bundling". To be more precise, they include unwanted apps in download installation setups of other software and hide information about it in their "Advanced", "Custom" and other settings. Quite often people leave these settings unchanged and that is how unwanted apps get permissions to be downloaded or installed together with some other, desired software. Deceptive ads cause unwanted downloads or installations by running particular scripts that are designed to cause it. However, it happens only when people click them.

How to avoid installation of potentially unwanted applications?

Software should be downloaded from official websites and via direct download links. Third party downloaders, installers, unofficial websites, Peer-to-Peer networks (like eMule, torrent clients) ant other tools or sources of this kind should not be trusted. Quite often they are used to distribute/promote unwanted software. Furthermore, software should be downloaded and installed properly: to do it properly, we advise to check all "Custom", "Advanced" and other settings that are available in any download or installation setup. If they contain offers to install or download unwanted software, then they should be dismissed before completing download or installation process. Furthermore, advertisements that are displayed on questionable websites should not be clicked. They often cause redirects to untrustworthy, potentially malicious websites or trigger unwanted downloads, installations. Browsers that opens unreliable websites or/and display intrusive ads usually do that because of some unwanted apps that are installed on them. In order to solve this problem we advise to remove all unwanted, unknown or suspicious extensions, add-ons or plug-ins that are installed on a browser and apply this to programs of the same kind that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
