How to uninstall ExtendedTech from a computer

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

What kind of application is ExtendedTech?

While testing the ExtendedTech application, our team discovered that it displays intrusive advertisements. Therefore, we classified this app as adware. It is common for adware to be promoted and distributed using questionable (often deceptive) methods. Thus, users often download and install it inadvertently.

ExtendedTech adware

ExtendedTech adware in detail

ExtendedTech bombards users with advertisements that can open potentially malicious web pages. Those ads can open websites designed to lure visitors into calling fake technical support numbers, downloading shady applications, providing sensitive information (e.g., credit card details, ID card information), etc.

Moreover, ads displayed by advertising-supported software can be designed to cause unwanted downloads and installations by running certain scripts. Thus, it is strongly recommended not to trust ExtendedTech and its advertisements.

Another reason to remove ExtendedTech from the operating system is that sometimes apps of this type can read passwords, credit card details (and), or other personal information. Developers of untrustworthy apps may misuse obtained information for malicious purposes (e.g., to steal online accounts, identities, money, etc.).

More about adware

In addition to showing unwanted ads, adware can promote shady search engines by hijacking web browsers. Typically, browser-hijacking apps change the default search engine, homepage, and (or) new tab page. Using untrustworthy search engines can lead to potentially malicious sites. Thus, it is highly advisable to browse the Internet using legitimate search engines only.

More examples of apps similar to ExtendedTech are UniversalSource, EazyBit, and DefaultFormat.

How did ExtendedTech install on my computer?

Most users install adware via fake installers downloaded from shady websites, deceptive advertisements, and software bundles. In the third case, users cause unwanted installations when they do not deselect unwanted apps. Typically, installers containing unwanted apps have "Advanced", "Custom", or other settings allowing users to deselect optional installations.

How to avoid installation of unwanted applications?

Download applications from official pages and stores. Do not trust P2P networks, questionable pages, third-party downloaders, and similar sources to download them. Always check downloaders and installers for additionally included unwanted apps and deselect them. Do not trust ads on dubious pages or agree to receive notifications from web pages of this kind.

If your computer is already infected with ExtendedTech, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
