Suddenly it now takes more than a minute to load an Internet page.
If I try to update it, a window opens title Opera Installer showing "Thank you for choosing Opera" and "Downloading" but it just sits there.
Other browsers still work fine.
ALSO Adobe update fails - window says installation will start soon but it never starts.
Avast antivirus, Spybot S&D, Malwarebytes anti-malware
I wonder if something is blocking downloads? And why Opera slowed down.
