Virus? Windows Update has internet other apps don't

[jaredpaquet]

Windows update can download updates but no other programs can access internet. I have tried plugging in wired reinstalling drivers and using an external wifi adapter all same results.
Internet explorer says "Internet Explorer cannot display the webpage"
Google Chrome says "This webpage is not available"
Malwarebytes says when it tries to update "PROGRAM_ERROR_UPDATING (10054, 0, Connection reset by peer) An existing connection was forcibly closed by the remote host."
These errors occur in chrome and ie even when i try to connect to my routers gateway. I have tried to reset windows firewall using "netsh firewall reset". I have tried turning off my security software "Avast". I have ran avast boot time scan and full scan, i have also run malwarebytes full and flash scan all resulting in nothing found. However windows update can download updates.

You may want to make a system restore from a week before the problem began.

I do not have a restore point that goes back that far. I received the computer with this issue. I may just have to do a clean install I see that as a last resort because there are 100+ gb of data to back up.

See how it works in safe mode

I'm currently running a scan from another device, safe mode with networking still has same results

If you can do a clean install you can do a repair install, try that

If that does not work
You should be able to install Ubuntu, it is another OS. If you can install the problem is not with your computer.. Once it is installed back up your stuff.
Use Ubuntu Live CD to Backup Files from Your Dead Windows Computer
