LaunchHistoryResults adware in detail

Clicking advertisements (e.g., banners, coupons, pop-ups) generated by LaunchHistoryResults can open untrustworthy websites. Clicking them can open pages designed to trick visitors into providing sensitive information, downloading potentially malicious applications, etc. Moreover, it can cause unwanted downloads (or even installations).

It is worth mentioning that sometimes applications like LaunchHistoryResults promote fake search engines: they hijack web browsers by changing their settings (the default search engine, homepage, new tab page). Fake search engines tend to promote shady websites and (or) show results generated by untrustworthy search engines.

More about adware

Apps similar to LaunchHistoryResults can be designed to gather various information. Pretty often, these apps can access sensitive information such as credit card details, passwords, telephone numbers, etc. Either way, LaunchHistoryResults, and other apps of this type cannot be trusted.

More examples of advertising-supported apps InfoMajorSearch, NetDivision, and DomainNameProduct.

How did LaunchHistoryResults install on my computer?

It is very popular for adware to be distributed via deceptive pages offering to install updates for the Adobe Flash Player and similar sites. Apps of this type often get installed via fake installers. In other cases, adware is bundled with other software.

Unexpected installations occur after installing software without changing "Advanced", "Custom", or similar settings available in certain installers. Advertisements can cause unwanted downloads/installations too. They can be designed to run certain scripts.

How to avoid installation of unwanted applications?

Download applications from official websites and platforms. Avoid downloading them from questionable sources such as unofficial sites, third-party downloaders, free file hosting pages, P2P networks, etc. Do not click on shady ads, notifications displayed by dubious pages, and fake "Download" (or similar) buttons.

Check downloaders and installers for optional downloads and installations and deselect unwanted applications before installing (and downloading) software. If your computer is already infected with LaunchHistoryResults, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
