To find out how spyware is more dangerous, we must know what each term mean.
Adware is a software that automatically displays advertising material usually on a site that a user goes to.
Spyware is a unwanted software that steals your internet usage data and personal information.
So while Adware can be extremely annoying, it is not as potentially harmful as Spyware, which can steal your personal information and potentially ruin your life.
