StackMist adware in detail

StackMist can display advertisements designed to open a variety of untrustworthy pages. For instance, pages designed to lure visitors into agreeing to receive notifications, providing personal information, calling fake technical support numbers, downloading potentially malicious software, etc.

Some of the ads shown by StackMist may be designed to run certain scripts to start unwanted downloads and installations. Thus, it is highly advisable not to trust ads displayed by StackMist and similar applications. Another reason to remove StackMist is that it can read sensitive information.

We found that StackMist can read passwords, phone numbers, credit card details, and other sensitive data, and browsing history. Its developers may sell that information to third parties or use it to steal personal accounts, identities, money, etc.

More about adware

Adware can also function as a browser hijacker. It can promote shady (or fake) search engines by changing the default search engine, homepage, and (or) new tab page. Using shady search engines can lead to untrustworthy pages and issues related to online privacy.

Examples of apps similar to StackMist are WorldWideProjector, DominantDisplay, and OperativeInfluence.

How did StackMist install on my computer?

Apps like StackMist often are distributed via fake installers promoted on deceptive web pages (e.g., pages claiming that certain installed software is outdated. Also, unwanted installations can be caused via untrustworthy advertisements and installers containing additional applications.

When adware is included in installers, those installers have "Advanced", "Custom", or other settings that must be changed to avoid unwanted installations. Users install when they leave those settings unchanged.

How to avoid installation of unwanted applications?

Avoid downloads from unofficial pages, P2P networks, third-party downloaders or stores, and similar sources. Download apps from official pages and verified stores only. Check downloaders and installers for "Custom", "Advanced", or other settings and deselect unwanted apps before downloading and installing programs.

Do not trust advertisements on questionable web pages or allow such pages to show notifications. If your computer is already infected with StackMist, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
