Alt.Center is an adware-type program that delivers intrusive ads and collects data about a user. Despite all allegedly useful features, this potentially unwanted program provides no value to the user in general because it behaves intrusively and fails to leave the system when being asked.

  • location;
  • search queries;
  • viewed pages;
  • searched items, deals, offers;

Alt.Center is a program that frustrates people with its displayed content because banners, pop-up windows, and other commercial content fill up the screen and keep the user from accessing his/her favorite websites. Also, this content creates unwanted redirects to questionable or possibly malicious pages filled with promotional content. 

However, these symptoms are not the main reason you need to remove Alt.Center. More dangerous is the fact that adware[1] tracks that information about you since the initial infiltration. No matter how harmless it sounds, this data can later be shared with third-party companies and used for commercial or sometimes even malicious purposes.

All this is done with the purpose of generating revenue to virus developers.[2]
