Liveads.net is a dubious website that many users have reported being taken to through forced redirects. The website is associated with the generation of intrusive advertising materials, further redirects to suspicious domains, or using manipulative tactics to lure visitors into subscribing to its push notifications.
The only purpose of Liveads.net is to generate monetary gains for its creators by delivering intrusive ads. If the redirects to the website happen only once or twice, they may have been caused by a previously visited website. If you land on Liveads.net far more frequently, however, then this might be a sign that adware or a browser hijacker app has managed to sneakily installed itself onto the computer system.
The first step is to abstain from engaging with any of the ads presented by Liveads.net as they could lead to compromised or untrustworthy places, significantly increasing the security risks facing the user. If you have already been tricked into subscribing to any push notifications, make sure to revoke the permissions granted to the scam websites by navigating to the appropriate options section in your browser's Settings menu.
Do not forget to check your computer system for any PUPs (Potentially Unwanted Programs). Download a professional anti-malware product and let it perform a thorough scan. Delete any unfamiliar apps that come up in the scan results.
