Mhelper is a Mac application that users may find installed on their computers – it is located in ~/Library/Application Support/MHelper/ Initially, not many will know that the component is installed, and the only symptoms that users experience are occasional redirects to one of the following websites:


Additionally, the Mhelper virus also starts the automatic download of the promoted applications – Regclean Pro, Duplicate Photos Sweeper, or Wise Mac Care. We highly advise users refrain from installing any of the advertised apps, as they might not only fail to meet the expectations but also damage macOS, as there is no guarantee that the automatically-downloaded .pkg file is what it is promoted to be. Nevertheless, to stop Mhelper redirects and automatic prompts, you will have to terminate it from your computer.

Recovery & optimization Instead of relying on scareware applications that claim to speed up and restore your Mac, we advise choosing Reimage Reimage Cleaner Intego – this tool can free up space on the system without damaging library files and also get rid of various negative effects that macOS can suffer from after malware infection

Mhelper adware[1] might appear on the macOS after users install freeware or shareware from third-party sites. Quite often, installers bundle optional components that are just complementary and can be eliminated before being installed. Unfortunately, third-party developers often fail to adequately disclose optional programs and make users install them unintentionally. To avoid such consequences and apps like Mhelper from being installed without your permission, download apps from official sources only.

There are several other remnants of potentially unwanted applications (scareware)[2] like Mhelper that initiate unwanted behavior on macOS systems, including:

  • Mhptask
  • Maftask
  • Helpermcp
  • Spchlpr, etc.

All of these apps are the leftovers of potentially unwanted applications like Mac Clean Pro or Similar Photo Cleaner. Apple does not recommend using third-party software that claims to resize, delete or de-clutter photos from macOS library, as it might corrupt the related data. Besides, various fake system optimizers that might actually damage the system instead of fixing it. Thus, if you need reliable application that can remove various threats, and clean up space without damaging library files, download and install Reimage Reimage Cleaner Intego.

For Mhelper removal, we recommend deleting all the associated files and also scanning the computer with powerful anti-malware software. The latter is necessary to find out whether more stealthy PUPs or malware is present on the machine.

Beware of software bundling – a distribution technique that allows PUPs to slip in without your direct approval

Software bundling has been successful for years now, simply because users are not keen on paying close attention to downloading and installing new software, despite security experts'[3] warnings. In most cases, they simply click the “Next” button several times until the process is complete. However, this is the biggest mistake users make when installing new programs from third-party sources. Thus, always read through the installation instructions carefully, decline all the optional components, and always opt for Advanced/Custom settings so all the underlying content would be visible. Then, untick all the boxes that would otherwise allow the installer to install PUPs such as adware.

Gatekeeper usually warns users when an unauthorized app is trying to get installed on Mac – users are prompted to enter their passwords in order to proceed. Unfortunately, users sometimes get tricked into installing apps they are not sure about. This is especially common when users are told that they need to update Flash – a plugin riddled with vulnerabilities and soon-to-be-retired by Adobe. The truth is, most users do not need Flash installed in the first place. Additionally, if you are sure you need it, you should always patch it via the automatic updater or access the official website.

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant a full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. 

Nevertheless, there's a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various circumstances, malware is also one of the main culprits that can cause loss of pictures, documents, videos, and other important files. Potentially unwanted programs may clear files that keep the application from running smoothly.

More serious malware infections lead to significant data loss when your documents, system files, or images get locked. Ransomware is the one that is focused on such functions, so your device gets useless without access to needed data. Even though there is little to no possibility to recover after file-locking threats, some applications have features for such recovery in the system.

In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
