So, the not being able to log in thing got me thinking. I tried it on Chrome, done. Then noticed I was having issues on Sprint.com with Opera. Chrome, I got in. That made me wonder. So I ran Malwarebytes/ CCleaner. Rebooted. The hell? All but the Adobe Flash issue is fixed. I feel like an idiot. But like I said, this is a work computer, other than Fbook/Twitter etc, I don't do anything risky, but I picked up something anyway. The video thing is still there though. Didn't have to click to play Adobe Flash videos before, why now? Changed no settings.
Ugh, so, sorry for the rant on Opera, but the last thing I suspected was malware.
