Remove PowerLog and MacPerformance from MacOS

Also Known As: Ads by PowerLog
Type: Mac Virus
Damage level: Medium

What is PowerLog?

PowerLog is an adware-type app and part of the Pirrit family. After installation, PowerLog installs another app of this type called MacPerformance. This app forces browsers to open web pages that offer updates to software with fake tools. Adware is software designed to display various ads.

In some cases, these apps can be used to record user-system (and other) information. Typically, people download and install adware inadvertently. Therefore, these programs are categorized as potentially unwanted applications (PUAs).

PowerLog adware

Installed adware feeds users with advertisements that are displayed in the form of coupons, banners, surveys, pop-ups, and so on. People who click them are usually redirected to potentially malicious, untrustworthy websites, or they allow these ads to download (or even install) other unwanted applications that might be malicious.

Furthermore, these apps are often designed to collect IP addresses, geolocations, URLs of opened pages, entered search queries and other information relating to users' browsing habits. In some cases, PUAs are used to gather personal details. In any case, people who develop PUAs share the data with third parties who misuse it to generate revenue.

Some of the third parties might be cyber criminals. To avoid this situation, uninstall PowerLog and MacPerformance immediately. Note that MacPerformance asks users for permission to access and control browsers. If allowed, the program gains access to documents and data within the browser and permission to perform actions within the app.

There are many apps similar to PowerLog. Other examples are DisplayUpdate, PowerLift, and LightAgent. All display intrusive, deceptive ads that usually cause unwanted downloads, installations or redirect to dubious websites. Remove all adware, since it can lead to installation of other PUAs, problems with browsing safety, privacy, and so on.

How did PowerLog install on my computer?

Some PUAs can be downloaded from their 'official' websites, however, many people download and install them unintentionally, or inadvertently. People are tricked into these unwanted installations/downloads when developers use a deceptive marketing method known as "bundling".

They add PUAs to the set-ups of other, regular programs that people wish to download. Many people thus install PUAs together with normal software. This happens when they leave settings such as "Custom", "Advanced" (available in software set-ups) unchanged.

How to avoid installation of potentially unwanted applications

Download all files and programs from official websites. Other channels/tools such as Peer-to-Peer networks, unofficial pages, third party downloaders, etc., should not be used - these channels are used to distribute PUAs or even malware. Do not use third party installers.

Check software setups that contain "Custom" or "Advanced" settings and decline offers to download or install unwanted apps. Do not trust or click ads displayed on dubious sites (for example, those relating to gambling, adult dating, pornography, and so on).

Typically, they open untrustworthy or malicious websites, or run scripts that download or install unwanted, potentially malicious applications. To stop the browser from opening dubious sites or showing ads, uninstall all unwanted, unknown or suspicious apps (extensions, plug-ins, add-ons).

If that does not solve the problem, remove all programs of this kind from the operating system. If your computer is already infected with PowerLog, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
