Mediasvideo.world is yet another webpage trying to lure its visitors, through intrusive pop-ups, to hit “Allow” so it can send browser notifications. These push notifications will spam users with unwanted advertisements. The ads will then direct to malicious websites to get money from you or downloads which will infect your computer further.
Pop-ups from mediasvideo.world may also prevent you from changing your settings back. Mediasvideo.world is usually installed through bundled software without you knowing. It has to be removed immediately.
