More details about pages like checker-online[.]com

Typically, websites like checker-online[.]com are promoted through shady advertisements, pages, and potentially unwanted applications. It is worth mentioning that a big part of PUAs is distributed using questionable methods. Thus, most users download and install them inadvertently.

How did adware install on my computer?

Lots of PUAs are distributed through downloaders and installers for other programs that have "Advanced", "Custom" or other settings. Users download or install PUAs together with other programs when they do not change those settings (when they do not decline unwanted offers).

In some cases, users cause unwanted downloads or installations by clicking on advertisements designed to execute certain scripts and through fake installers downloaded from untrustworthy web pages.

How to avoid installation of potentially unwanted applications?

Download applications from official pages. Avoid using Peer-to-Peer networks, third-party downloaders, and other similar sources. Always check downloaders and installers for optional downloads and installations. Avoid clicking on advertisements that appear on dubious pages.

If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
