MacPerformance. How to remove? (Uninstall guide)

removal by Julie Splinters - - | Type: Adware

MacPerformance is a dangerous adware application that can expose personal details to cybercriminals

MacPerformance adware
MacPerformance is adware application that constantly shows pop-up messages, asking to grant it permission to access sensitive data

MacPerformance is an unreliable application that gets installed on macOS and iOS devices together with freeware and shareware apps. As soon as the potentially unwanted program[1] enters the computer, it scatters its files all over the system and starts its suspicious activity. By itself, the questionable application is not that dangerous, and can only show annoying pop-up notifications that look like legitimate Apple ones. MacPerformance asks users to give control to access various files, which would allow attackers read browsing and technical data, as well as account passwords and even banking information, and then send it off to a remote server. This cleverly engineered social engineering attack[2] might trick many users and result in stolen money or even identity theft.

Summary
Name MacPerformance
Type Adware/virus
Category Scam
Infiltration Software bundling 
Elimination Check our instructions below or use anti-malware software
Optimization Install Reimage to make sure your computer is repaired

MacPerformance is one of many scams that are trying to trick users into stealing sensitive information by mimicking legitimate Apple pop-ups – Apple wants to make changes is one of those. While these pop-ups might look legitimate, there is nothing safe about them, and users should learn how not fall right into crooks' trap. To remove MacPerformance virus, you will have to eliminate the adware, and it might get tricky. However, we provide full instructions below. 

What makes MacPerformance scam believable is its cleverly placed names of certain files. First of all, the name of the adware might make users believe that it is a legitimate application, as it incorporates “Mac” in it. Also, please look at the message itself:

“MacPerformance” wants access to control “Google Chrome”. Allowing control will provide access to documents and data in “Google Chrome”, and to perform actions within the app
Don't Allow                OK

While many users are baffled what MacPerformance is, digging deeper reveals that the application sits under the Library > UpdateMac > MacPerformance. Therefore, many people might still think that there is nothing wrong with this folder. However, it is an adware that will continue to spawn pop-ups.

Also, even if you pick “Don't Allow” option when the fake alert shows up, it will continue its activity. Only MacPerformance removal will stop the fake notifications and prevent crooks from accessing sensitive information. By the way, it does not matter which browser you use, Google Chrome, Safari, Mozilla Firefox, or other, the pop-up can show the browser name accordingly.

To conclude, MacPerformance is malware that can steal your personal data which can later be traded in the black market. Do not trust these pop-ups and get rid of the adware as explained below. We also recommend scanning your device with Reimage to make sure that all the damage done by the virus is fixed.

Software bundling can propagate adware programs

Since adware is usually undesirable software, its creators need to make sure that it is distributed to as many computers as possible. And one of the best ways to do so is by bundling programs. This technique has been used by freeware and shareware developers and proves to be successful, the reason for that being lack of users' attentiveness. They are often quite oblivious when it comes to new software installation, and do not pay much attention to it – skip steps and don't read the instructions properly and, most importantly, select Recommended/Quick settings.

The best way to avoid adware is to be wary during new software installation. Even if it comes from an allegedly trusted source, such as Download.com or CNET, always opt for Advanced/Custom mode to make sure that no optional elements enter your computer. 

Experts explain[3] that adware mostly hides under “useful” applications, such as media players, PDF converters, browser extensions, system optimizers, and similar programs. Its functionality may seem useful, but all you get is never-ending adverts that clutter your browsers and even compromise your privacy. Thus, we recommend reading up reviews before installing new software you are not familiar with.

Remove MacPerformance malware from your Mac

As we already mentioned, you have to remove MacPerformance virus to stop the pop-ups from showing up. There are several actions you need to perform to make sure that the annoying pop-ups do not show up again. First of all, you should check our instructions below on how to complete MacPerformance removal by putting it into Trash. However, you can also use automatic tools that focus on PUPs – you will not have to worry about anything.

After you get rid of the MacPerformance adware and reset your browsers, you should also stop the launch process of the program. Go to System Preferences > Accounts>  Login Items. Now find MacPerformance and press the “-” button.
