Cannot install F-Secure Anti-Virus on Windows 8.1
My friend bought a new Lenovo Yoga 3 laptop so I uninstalled previously installed McAfee Internet Security and ran the McAfee Cleanup tool then disabled Windows Defender. After launching the networkupgrade exe I got in the email I get an error saying "F-Secure Internet Security upgrade failed uninstall previous installation first". There is no previous installation of F-Secure and why does it say F-Secure Internet Security in the installer we downloaded the AV installer!
Please help now I feel like an idiot after having had praised F-Secure and recommending it for her!
