How to uninstall LegionSuites application from a computer

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

What kind of application is LegionSuites?

LegionSuites is an application that generates revenue for its developer by bombarding users with various advertisements. Software of this type is called adware. We discovered LegionSuites after examining a fake installer that is supposed to update the Adobe Flash Player.

LegionSuites adware

LegionSuites adware in detail

We classified LegionSuites as adware because it shows intrusive ads such as pop-ups, banners, surveys, coupons, and other advertising material. Those ads can open shady/potentially malicious websites (e.g., phishing pages, technical support scam sites, pages offering to download questionable applications).

It is also possible that ads displayed by LegionSuites may cause unexpected downloads and installations. In addition to displaying unwanted ads, LegionSuites may collect browsing data and other (possibly sensitive) information. Depending on the gathered data, it may be misused for marketing purposes, sold to third parties, used to steal identities, online accounts, etc.

More about adware

Sometimes, adware can modify the web browser's settings to promote a fake search engine. It can hijack a browser by changing the homepage, default search engine, and new tab page. It is not safe to use fake search engines since they can generate misleading results and show results generated by other untrustworthy search engines.

More adware examples (apps similar to LegionSuites) are AuroraShack, PowerSet, and ValueFlip.

How did LegionSuites install on my computer?

It is common for apps like LegionSuites to be installed via fake installers downloaded from deceptive pages (e.g., websites claiming that the installed Adobe Flash Player is out of date). Also, users often install adware via software bundles and ads designed to run certain scripts.

When developers include adware in installers, users cause unwanted installations when they do not change the provided settings. Users install adware alongside other software when they leave "Advanced", "Custom", or similar settings in installers unchanged.

How to avoid installation of unwanted applications?

Download software (and files) only from official web pages (and legitimate stores). Do not use unofficial pages, P2P networks, third-party downloaders (and stores) and similar sources to download them. Also, check downloaders and installers for "Custom", "Advanced", or other settings and deselect unwanted apps before finishing downloads/installations.

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