Can I run Avast alongside Windows Defender in a Windows 8.1 computer?

No. Disable Windows Defender then install avast. It's a very bad idea to
have two resident anti-viruses at the same time.

Read this for more information.

Thanks for your reply.  I am aware of the problems caused by running two AV's but they describe Defender more like anti spyware software then AV and I was not sure if it could be kept active to be run as a stand alone.

On a Win8 system, Windows Defender should automatically disable itself when you install avast [or any other recognized anti-virus program].
Lenovo T530 laptop, Intel Core i5-3320M @ 2.60 GHz, 8GB RAM, Windows 7 Pro SP1 (64-bit), avast! 17 Free, MBAM3 Pro, Windows Firewall, MVPS HOSTS file, OpenDNS Family Shield, Zemana AntiLogger Free, SpywareBlaster, IE11 & Firefox [both using WOT (IE set to WARN, FF set to BLOCK)], WinPatrol PLUS, uBlock Origin, MBAE, MCShield, CryptoPrevent, SAS (on-demand scanner). 
[I believe computer-users who sandbox (Sandboxie) are acting prudently.]
