What is n121adserv?

N121adserv is an advertising platform that is NOT a virus. However, ads that it causes can not be treated as harmless because they belong to third parties that are interested in increasing their visitors’ traffic and sales. Beware that you can never be sure about the safety of these ads because the publisher does not take any responsibility for the safety of its ads. So, we highly recommend ignoring them and also avoiding websites that they try to redirect you to. Unstoppable appearance of ads and constant redirects can also explain one little thing – why did people start using “N121adserv virus” term. If you are one of those who have noticed ads by this service on your web browser, you should think about your recent downloads. Most probably, you have installed an adware-type program in a bundle with some download manager, PDF creator, video streaming software and similar program. Such adware is compatible with the most popular web browsers, including Google Chrome, Mozilla Firefox or Internet Explorer. If you want to get rid of n121adserv ads, you have to remove this potentially unwanted program. The easiest way to find it is to run a full system scan with Reimage or other reliable anti-spyware.

To be sure that each of its related components was eliminated, you should opt for automatic removal option. Programs that are listed down below will show you the real danger that is hiding on your computer.
