'Can't play this video!' Browser Notification Page

The 'Can't play this video!' browser notification page is a misleading error message that the users may encounter when they attempt to play a video on a shady website. These messages use basic social engineering tricks to get the users to give the website certain permissions such as the ability to display notifications in their Web browser. The page may claim that the user must click the ‘Allow’ button to allow the page to play the video in question but, in reality, this action would give the page permission to display notifications while the user is browsing other websites.

While this change is not harmful, it may have a negative impact on the user’s ability to browse the Web, since some pages may use these notification permissions to display a large number of advertisements and sponsored content that are likely to bother the user a lot.

In some worse scenarios, tricks like the one seen in the 'Can't play this video!' browser notification page may end up being used to get users to download dubious executables that might be meant to bring adware to their computers. We advise you to never download files from untrustworthy Web destinations, as well as to make sure that your computer is protected by a reputable anti-malware tool that will keep you warned if you end up browsing suspicious websites.

If you have allowed a page to display in-browser notifications accidentally, then we suggest that you take a close look at your Web browser’s Privacy settings and remove the permissions of any unfamiliar sites.
