Its possible that your PC is infected with an adware that opens misleading pop-up ads. To clean your computer and remove fake security alerts from Edge, I suggests use the free utilities AdwCleaner and MalwareBytes Anti-Malware. Follow the steps below.
- Please download AdwCleaner by Xplode from http://www.myantispyware.com/download/adwcleaner . Close all open programs. Double click on AdwCleaner.exe, then select I agree if it appears.
- Click Scan. When the scan of your PC has completed. Click on Clean button.
- Download MalwareBytes Anti-Malware from http://www.myantispyware.com/download/malwarebytes-anti-malware . Once downloaded, run “mbam-setup” to start the installation of Malwarebytes Anti-Malware. It will open the Malwarebytes Anti-Malware Setup Wizard. Follow the prompts.
