To2s[.]biz and similar pages in general

Users do not visit websites like to2s[.]biz on purpose. They open them by clicking shady ads or while visiting other dubious pages. In other cases, these sites get opened by installed potentially unwanted applications (PUAs).

How did adware install on my computer?

Users often download or install PUAs via downloaders or installers for other programs - when they download or install programs without deselecting optional downloads or installations. It can be done using available "Manual", "Advanced", or other settings that downloaders and (or) installers used to distribute PUAs have.

Also, users download or install PUAs by clicking on advertisements designed to run certain scripts and through fake installers. Most of the fake installers are promoted on various deceptive websites.

How to avoid installation of potentially unwanted applications?

Downloaders and installers with "Custom", "Advanced", "Manual", or similar settings, or ticked checkboxes can include optional downloads or installations. Users should check those settings before downloading or installing programs.

Files and programs should be downloaded from official websites, via direct links, and not from other sources (like third-party downloaders, unofficial pages). It is also recommended to avoid clicking on advertisements displayed by dubious pages, PUAs.

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