Adware: sneaks into the computer without user's permission

One of the most successful distribution technique which is highly used by cybercriminals to spread potentially unwanted programs is called bundling. Similar to other PUPs, adware enters the system in the same way — inattentive people install it during the installation of free applications.

This happens when users rush to finish the procedure and pick Quick or Recommended parameters of the installer. This way, the adware is hidden among the optional components and can enter the system without direct user's permission. For this reason, we always advise people to install software only with Advanced or Custom settings.
