My friend has asked me to fix their computer and I have run out of ideas.
My friend informed me that upon uninstalling Avast for her Windows 8 computer, she was unable to connect to the internet. I verified that the issue was computer side by trying to connect to both my home network, wifi hotspot. Ran the troubleshooter, only suggestions were rather irrelevant (connect to the network automatically). Updated the driver, downgraded the driver, uninstalled the driver, flushed the DNS, reset the TCP/IP settings, reset the BIOS, recovered to an older recovery point, deleted the network profile, turned off the adapter power saving setting, tried a static IP address, disabled the firewall, rebooted into Safe Mode with Networking to see if that would give me access - simply nothing I tried got me past the limited connectivity issue.
There are many instances of this issue on the AVAST forum (for example: https://forums.techguy.org/threads/...-avast-internet-security-uninstalled.1050440/). I attempted to use AVAST's uninstall program to clear the issue, that did nothing. I reinstalled AVAST to see if that would give me internet access, again nothing. I am totally stumped here. Any ideas?
I posted the problem to another forum and they weren't able to come up with any solutions. You can see what we tried here:
