The genuine wwahost.exe file is a software component of Microsoft Windows Operating System by Microsoft Corporation. "WWAHost.exe" is an important core component of Microsoft Windows 8, 8.1, and 10, and should not be removed. It resides in "C:\Windows\System32". (On 64-bit machines that is its 64-bit version and its 32-bit version is in "C:\Windows\SysWOW64"). Metro and Modern apps, introduced beginning with Windows 8, are often written in JavaScript, which has no I/O capabilities of its own for networking, file access, or a GUI, and must execute within a Web browser or within "WWAHost.exe", which offers more functionality than Internet Explorer. Although it can host JavaScript objects, similar to the way "svchost.exe" does for services written as DLL's, "WWAHost.exe" cannot host Java, ActiveX, Adobe Flash Player, or Silverlight objects, or generally any object not specified in the HTML5 schema.
WWAHost stands for Windows Wrap-Around Metro App Host

WWAHost.exe is currently suspended. AVG and AVIRA are my firewall; internet protection programs running... are they causing the suspense... WILLIAM ASHE

WWAHost.exe hosts and executes all modern Windows 10 apps which built with HTML and JavaScript. This process provides a superset of functionality greater than that provided by the Microsoft Internet Explorer browser. Therefore if a web app runs under Internet Explorer it can also easily be run under WWAHost.exe. Alex
