Recent glitch preventing me from logging on to my computer

9. I'm starting to think it's some malware trying to get in and my computer security is fighting it

This morning I checked and started the computer. Things seemed pretty normal. I had lost my internet connection overnight. I connected again and pretty soon the pop up appeared again, blinking away and preventing me from taking any actions. So it appears to not affect me when offline. But now that I’m online it prevents me from doing anything including cancelling the connection. I guess I’ll have to wait till I drop the connection or maybe I can turn off the modem. It appears that I can do stuff when I’m offline.

I caught a view of an app called wavebrowser. I looked it up online and it’s identified as malware. My theory is it’s trying to complete its uninvited installation and my computer’s security is trying to prevent that, thus the stuttering screen.
