Hi Arian, there are a lot of risks related to Tidy Network adware - this potentially unwanted application generated various rogue ads that can lead to malware or ransomware infections. You should uninstall this adware from your computer as soon as possible. Notice that commonly this PUP comes bundled with other adware so you should scan your computer with Spyhunter and AdwCleaner (https://toolslib.net/downloads/viewdownload/1-adwcleaner/) to make sure your PC is clean.
