How to remove LaunchSystem from Mac?

What is LaunchSystem ?

LaunchSystem functions not only as adware, but also as a browser hijacker and a data collector. It serves advertisements, promotes a fake search engine (it address) by changing browser settings and gathers sensitive information. As a rule, users download and install applications like LaunchSystem unknowingly, for this reason they are categorized as potentially unwanted applications. It is known that this particular app is distributed via deceptive (fake) installer that is disguised as an installed for Adobe Flash Player.

LaunchSystem  adware

Typically, applications like LaunchSystem serve coupons, banners, surveys, pop-ups, and/or other ads of other type. Quite often users who click those ads end up on various untrustworthy web pages. Sometimes by doing that they allow those ads to execute scripts that are designed to download and/or install unwanted, potentially malicious software. As mentioned in the introduction, LaunchSystem is designed to promote a fake search engine. After installation it changes the address of a default search engine, homepage and new tab to d2sri.com. If used to search the web, d2sri.com redirects users to search.yahoo.com - it provides results generated by Yahoo. It is common that users cannot remove the address of a fake search engine from browser settings unless a browser hijacker that is designed to promote it is no longer installed on a browser. Furthermore, LaunchSystem can read sensitive information from browsers such as passwords, telephone numbers, credit card details. Its developers could misuse collected data to steal personal accounts, make fraudulent purchases, transactions, steal identities, send malspam campaigns, and/or for other malicious purposes.

How did LaunchSystem install on my computer?

LaunchSystem is distributed via fake installer that is designed to look like an installer for Adobe Flash Player. It is common that such installers are used to distribute not only adware-type apps (or other PUAs) but also malicious programs (like ransomware, Trojans). Also, quite often PUAs are distributed by using a deceptive marketing method called "bundling". To be more precise, by including PUAs in download and/or installation setups of other programs as extra offers. Typically, offers to download and/or install those apps can be declined in "Custom", "Advanced" and other similar settings of setups, or by unticking certain checkboxes. When users finish downloads and/or installations without doing that, they allow for included PUAs to be downloaded and/or installed too. Also, unwanted downloads and installations can be caused by clicking deceptive advertisements that are designed to run certain scripts.

How to avoid installation of potentially unwanted applications?

It is advised not to complete any download and/or installation process without checking if a setup has "Custom", "Advanced and other similar settings and if they can be used to decline offers to download and/or install unwanted apps. Software (and files) should be downloaded from official websites and via direct download links. It is recommended not to use third party software downloaders, installers, Peer-to-Peer networks like eMule, torrent clients and so on. Also, it is not safe to click advertisements that appear on questionable web pages - more often than not they are designed to open other unreliable, dubious websites or even cause download and/or installation of some unwanted software. And finally, there should not be any unwanted, suspicious apps (extensions, add-ons, or plug-ins) installed on a web browser, and/or programs of this kind installed on the operating system. If your computer is already infected with LaunchSystem, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
