How to remove Ouo.io

What is Ouo.io

Ouo.io is a bogus website, that is a part of a huge advertising network. It displays fake pages of Adobe Flash updates, streaming sites, download portals and claims to provide access to restricted content after allowing notifications. Push-notifications is a feature in modern browsers, that allows users to get announcements about important information from online newspapers, Youtube, or social networks. This function is exploited by adware to push promotional information via this channel. If you see ads, pop-ups, or notifications from Ouo.io, there is a high possibility of malware infection or browser’s settings hijack. In this tutorial, we will analyze all possible reasons and provide solutions to remove Ouo.io and restore browser settings for normal operability.

How Ouo.io infected your PC

There can be several reasons for Ouo.io ads, appearing on your PC. Firstly, your PC, Mac or Android are infected with adware (malicious browser add-on, potentially unwanted application installed). Secondly, it may just show notifications, after users accidentally allowed Ouo.io to show them. Usually, it pops up when a user visits sites with adult content, pirated software, or other types of doubtful sites. Browser is redirected to the page with the “Allow” button, which should show hidden content, but, in fact, subscribes the user to push notifications. It also displays a standard browser dialog box to allow notifications from Ouo.io. When users click the “Block” button, it redirects the browser to another random domain, then to another and it never stops, until the user accepts it or closes the browser window. To avoid this, always use ad-blocking software, for example, AdGuard (AdGuard for Mac). To remove adware from your PC, use one of the best anti-malware applications: SpyHunter or Malwarebytes.
