Basically, this is what happened with minimal scrutinous details:
Avast! detected malware threat and offered to "lock in Chest."
After this happened, I was prompted to restart my system and
perform a Boot-Time scan prior to rebooting it. I obliged,
and let the Boot-Time scan run. After returning, my internet connect
was disabled, as well as my Internet protection shields.
Also, internet in the rest of my house works, and my computer is bug free.
I've called my ISP, so it's not the connection error either.
Is this a common
problem, and how do I diagnose and fix it?
TL;DR: Internet worked fine. After malware threat, boot-time scan was performed.
Boot-time scan disabled internet connection. How do I fix it?

What was the file name and location ?
Have you looked in the avast virus chest (avastUI > Maintenance > Virus Chest, this should give the file name and original location ?
-
exactly what happened to me today.
Maybe your bootscan has deleted tcpip.sys file (if patched tcpip with wxp).
I resolve with tool I took in the topic:

Which is why I asked what the file was and its location, if it was tcpip.sys and it is in the chest then it can be resolved, by restoration and exclusion.

I don't think it's connected - the boot-time scanner wouldn't delete the tcpip.sys file (just like an ordinary scan wouldn't, only the anti-rootkit scan did).
