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:
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.

Mhelper adware 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) like Mhelper that initiate unwanted behavior on macOS systems, including:
- 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 ReimageIntego.
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' 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.

How to prevent from getting adware
Protect your privacy – employ a VPN
There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is 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.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
