What is UpgradeSearchSystem?
UpgradeSearchSystem is one of many potentially unwanted applications (PUAs) - adware-type apps that supposedly improve the browsing experience.
In fact, this app delivers no useful features. UpgradeSearchSystem serves intrusive advertisements and collects information relating to users' browsing habits. Typically, people download and install adware (and other PUAs) inadvertently.
Installed adware (in this case, UpgradeSearchSystem) displays advertisements in the form of coupons, banners, surveys, pop-ups, and so on. Typically, these conceal underlying content of visited websites and, if clicked, redirect users to dubious websites. In some cases, they execute scripts that cause download/installation of unwanted applications.
In any case, it is not safe to click such ads. Furthermore, adware-type apps often collect details such as IP addresses, entered search queries, addresses of visited pages, geolocations, and other browsing data. In some cases, they can access sensitive information.
People behind them (developers) sell the information to third parties who misuse it in other ways. Therefore, the data could fall into hands of cyber criminals. Do not download or install adware, since users risk becoming victims of identity theft, experiencing problems relating to privacy, browsing safety, and other issues.

These apps supposedly improve the browsing experience and deliver various features, however, most are useless, deliver no value, and cause only problems. They are designed only to help the developers to generate revenue by serving ads and collecting data.
How did UpgradeSearchSystem install on my computer?
Typically, people download and install PUAs unintentionally by clicking deceptive advertisements or when developers distribute them using a marketing method known as "bundling".
They use this method to trick people into downloading and installing PUAs together with other, regular software - developers include the apps into the download/installation set-ups of other programs and hide related information in settings such as "Custom" and "Advanced".
In many cases, people allow PUAs to infiltrate when they leave these settings unchecked and unchanged. Downloads and installations through deceptive ads occur when the ads execute certain scripts.
How to avoid installation of potentially unwanted applications
Download all software from official websites and via direct links. It is not safe to download or install programs through third party downloaders, installers, unofficial websites, Peer-to-Peer networks (torrent clients, eMule), and so on.
Check "Custom", "Advanced" and other settings of all download or installation setups and decline offers to download or install unwanted apps before completing the process. Intrusive ads that are shown on dubious web pages tend to open other, similar websites or cause download/installation of unwanted software.
Therefore, do not trust or click these ads. Remove any unwanted, unknown or suspicious extensions, add-ons or plug-ins installed on the browser.
The same should be applied to software of this kind that is installed on the operating system. If your computer is already infected with UpgradeSearchSystem, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
