Mhelper is a suspicious app that initiates direct downloads of potentially unwanted programs

Mhelper
Mhelper is a suspicious application that gets installed with other unwanted programs from third-party sites

Mhelper is a Mac application that users may find installed on their computers – it is located in ~/Library/Application Support/MHelper/MHelper.app. 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:

  • jaininfotech.com
  • duplicatephotossweeper.com
  • wisemaccare.com

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.

Type Mac virus, redirect virus, adware
Infiltration In most of the cases, users infect their Macs after installing software from third-party sources. Additionally, adware or malware might be installed on the system after users get tricked by fake Flash updates
Associated websites jaininfotech.com, duplicatephotossweeper.com, wisemaccare.com
Symptoms Users are randomly redirected to sites that promote Regclean Pro, Duplicate Photos Sweeper, or Wise Mac Care. Additionally, the installer file (for example, wisemaccare_rwaff.pkg) is downloaded automatically
Termination  Get rid of Mhelper by deleting all the associated components as per the instructions below. Alternatively, you can scan your machine with anti-malware software that detects potentially unwanted apps
Recovery & optimization Instead of relying on scareware applications that claim to speed up and restore your Mac, we advise choosing Reimage Reimage Cleaner – 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 .

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.
