Can anyone explain why this is happening? 100% CPU usage, maxed out WAN interface w/ screenshot

Just bought the router a few weeks ago and everything went well.  

 

The last few days, I get this: https://i.imgur.com/XwkwnZ3.jpg

 

The internet slows to a crawl and will eventually be inaccessible.  I can power cycle the router and everything works for a few hours and then randomly it locks up again. 

 

I removed all devices off the router and a switch it was hooked up to it and directly connected a laptop with just a Linux Live CD distro to do some basic diagnostics.

 

When I access the web GUI I can see the bandwidth hit ~350Mbps-450Mbps and 100% CPU usage.  I only have a 150Mbps up/down from FIOS.  top shows the ubnt account running "something", but in the COMMAND column it is blank.  I seached the PID and got next to nothing.  I also checked crontab and found nothing there from a cursory look.

 

This problem seems to happen randomly as well.  

 

 

I highly suspect that my EdgeRouterX is either compromised with malware or it is defective.

 

Any insight would be appriciated.
