14 DAY TRIAL // avast! Antivirus is one of the security products that has already received support for Windows 8.1, but a number of compatibility issues is affecting older versions of the application.
AVAST Software has revealed that all users who want to install Windows 8.1 first need to upgrade to Avast! 2014 and only then deploy Microsoft’s new operating system. Otherwise, Windows 8.1 will automatically disable the anti-virus due to a number of compatibility issues.
“Avast! 2014 has Windows 8.1 certification which ensures that it meets compatibility standards and performs well on the Windows platform. Older versions of avast! Antivirus do not carry that certification, so if you update to Windows 8.1, it will disable avast! and you will be unprotected,” the security vendor said in a short statement.
Windows 8.1 already comes with built-in anti-virus protection thanks to Windows Defender, but the application is automatically disabled once you install a third-party security product such as avast!.
