What kind of software is OnlineClient?
OnlineClient is an advertising-supported application. The purpose of this app is to generate annoying advertisements. Our team has discovered OnlineClient while examining deceptive websites. Typically, apps of this type are promoted and distributed using deceptive methods.
OnlineClient adware in detail
Clicking on advertisements displayed by OnlineClient can open untrustworthy pages asking to provide sensitive information (e.g., credit card details, passwords). Also, it can lead to websites used to promote shady apps, various scams, and other shady pages. In some cases, clicking on ads generated by adware can download or even install other unwanted applications.
We have examined many apps similar to OnlineClient and found that some do more than display advertisements. Some of those apps can hijack web browsers to promote fake search engines. They change the web browser settings to force users to browse the web with fake search engines.

Adware in general
Adware can be promoted as useful, legitimate software. However, it displays intrusive advertisements that can open untrustworthy pages. Sometimes, adware can access sensitive information. Thus, it is strongly recommended not to install adware and remove already installed adware as soon as possible.
More adware examples are TrackFrequency, PlusTarget, and HotComplete.
How did OnlineClient install on my computer?
It is common for adware to be distributed using deceptive websites (e.g., via websites claiming that Adobe Flash Player is outdated). Another popular distribution method is to bundle adware with other software. Users install adware alongside other software when they do not change "Advanced", "Custom", or other settings before completing installations.
In some cases, adware installs after clicking advertisements designed to run certain scripts. Either way, most adware installations are caused unintentionally/unknowingly.
How to avoid installation of unwanted applications?
Do not download applications from questionable sources (e.g., unofficial pages, third-party downloaders, P2P networks). Use official pages and platforms for downloading them. Also, do not click on advertisements displayed on torrent sites, adult pages, and other dubious pages (or allow such pages to show notifications).
Deselect unwanted downloads and installations (by changing the available settings) before downloading and installing software. If your computer is already infected with OnlineClient, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
