I have a similar problem. Can I post in here or do I need to make a new topic?
I was on the web looking through facebook, I followed a link to a site. While there, a suspicious pop-up came up. I immediately stopped and tried to close it, but I believe I got infected. It was at this point that my internet indicator in the system tray (I was connected through my wireless router) displayed a red x over it. I was still connected to the internet and able to surf around.
When I clicked on the network connection in the system tray and selected the connection I was using, it said my current settings didn't match those of the connection.
I went to the "manage internet connections" and deleted the connection profile, then I tried to reconnect to that connection in the list of available wireless connections. It would not accept my password. However, I know the wireless router is working and I know that my password is correct, because I can connect to my wireless router with my other devices... the password and the internet were both working on other devices, but my seemingly infected desktop was just telling me that my security passphrase for the wireless connection was incorrect. It didn't even appear to query the wireless, it IMMEDIATELY told me the passphrase was incorrect.
At this point I did a quick scan with Avast (free) and Malwarebytes (free). Malwarebytes found a bunch of things and removed them, but that didn't seem to help.
I restarted my computer, this time in Safe Mode with Networking, I re-ran Malwarebytes and it didn't find anything.
The issue persists.
