Questions about MacPerformance

MacPerformance is an adware application that is created for macOS and iOS devices. It often gets into the system with the help of software bundling, and some might also find additional adware such as Alpha Shoppers, EasyDirectionsFinder or other shopping companions, media players, PDF converters. etc. The potentially unwanted program[1] injects various files and performs system changes in order to gain persistence. Besides, it can disable you from opening needed apps. While MacPerformance is asking users to give control to access various files, it could be dangerous as it could allow attackers to 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.

Name MacPerformance
Type Adware/PUP/Apple virus
Main symptoms Causes annoying ads, disables applications from opening, tracks data without user's approval and sends it to its developers
Connected to Alpha Shoppers, Easy Directions FInder, other potentially unwanted apps from Pirrit family
Infiltration Software bundling which allows installing apps onto the system without a clear permission
Elimination Check our instructions below or use anti-malware software
Optimization Install Reimage Reimage Cleaner Intego 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, e.g. Apple wants to make changes, Your Mac is infected with 3 viruses, Your Mac might be infected. 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 find and eliminate the adware from the system, 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”, “Apple”, and similar terms, such as the ones incorporated into messages below:

“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

“MacPerformance” can't be opened because Apple cannot check it for malicious software

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 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 Reimage Cleaner Intego to make sure that all the damage done by the virus is fixed.

Software bundling is a widely used PUP distribution technique

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[3] or CNET, always opt for Advanced/Custom mode to make sure that no optional elements enter your computer. 

Experts explain[4] 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.

MacPerformance pop-upsMacPerformance pop-up may show up at any time if an adware is installed on the Mac machine, although most users see the message as soon as they try to open Safari browser

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
