What is an adware
Pop-ups and redirects like Yealnk.com are usually occurring because of some ad-supported program. You authorized the ad-supported program to set up yourself, it occurred during a freeware installation. Not everyone will be aware of the signs of a contamination therefore, not all users will come to the conclusion that it’s indeed an adware on their machines. What the advertising-supported program will do is it will make invasive pop-up advertisements but since it isn’t a dangerous computer virus, it won’t directly danger your machine. However, if it managed to redirect you to a harmful site, ad-supported software could bring about a much more severe threat. An adware will not be valuable to you so we encourage you erase Yealnk.com.
