How to remove AddUpgrade from Mac?

What is AddUpgrade?

AddUpgrade is program which is classified as adware and potentially unwanted application (PUA). After installation adware-type applications feed users with various forms of advertisements. Also, it is common that they are designed to collect various information. Applications like AddUpgrade are called PUAs because people often download and install them inadvertently (unknowingly).

AddUpgrade adware

Typically, software like AddUpgrade is designed to serve advertisements that are displayed in forms of banners, pop-ups, coupons, surveys, and so on. Users who click those ads tend to end up on various untrustworthy, potentially malicious websites or allow them to run scripts designed to cause download and/or installation of some PUA. AddUpgrade operas not only adware but also as a browser hijacker: it is designed to promote akamaihd.net address by changing browser's settings. Typically, apps of this type promote fake search engines by modifying settings such as address of a default search engine, homepage and new tab. Such search engines often provide results generated by some other search engine. Akamaihd.net redirects users to search.yahoo.com (or either to Safe Finder website which, in turn, redirects to Yahoo), it provides results generated by Yahoo. Quite often adware is designed to collect various information related to user's browsing habits as well. For example, details like geolocations, entered search queries, addresses of visited pages, IP addresses, etc. Research shows that AddUpgrade is designed to record personal, sensitive information such as passwords, credit card details, telephone numbers. It is very likely that its developers may attempt to generate revenue by selling gathered data to third parties (potentially cyber criminals) who could misuse it in other ways. Users who have AddUpgrade installed on a browser and operating system risk to become victims of identity theft, suffer monetary loss, experience problems related to browsing safety, privacy, and other serious issues. Therefore, if AddUpgrade or any other app of this type is installed on a browser and/or computer, then it should be uninstalled from it as soon as possible.

ProcessLocator, SoloProcess, BrowserProduct are adware-type applications too. However, there are many other apps of this type. What most of them have in common is that they are designed to feed users with advertisements. Quite often they operate as information tracking tools as well. In one way or another, most oft them do not deliver any value and can lead to various problems. For these reasons adware should never be downloaded and installed.

How did AddUpgrade install on my computer?

It is common that developers distribute PUAs by including them in various download and/or installation setups of other software. In most cases offers to download and/or install potentially unwanted apps can be found in their "Advanced", "Custom" and other similar settings. The problem is that not all users check those settings. In other words, they leave them unchanged. By leaving default settings unchanged they often allow for included PUAs to be downloaded and/or installed alongside with other, intentionally downloaded and/or installed software. PUAs can get installed through deceptive ads that are designed to run certain scripts as well. However, such ads cannot cause that without being clicked.

How to avoid installation of potentially unwanted applications?

Users who download and/or install software through untrustworthy sources such as third party downloaders, installers, Peer-to-Peer networks like torrent clients, eMule, unofficial pages, etc., often download and/or install PUAs as well. Therefore, all software should be downloaded from official pages and via direct download links. Furthermore, download and installation setups that contain settings like "Advanced", "Custom", "Manual" should be checked for offers to download and/or install additional, unwanted software. Those offers should be declined before finishing download and/or installation processes. Intrusive advertisements on shady pages often open potentially malicious pages. Also, they can cause unwanted downloads, installations. For these reasons such ads should not be clicked. And finally, if there are any unwanted extensions, add-ons or plug-ins already installed on a web browser, then they should be removed as soon as possible. The same should be done with programs of this kind that are installed on the operating system. If your computer is already infected with AddUpgrade, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
