I use the free AVG. After trying AVG PC Tune-Up (the trial period has ended), there are some sites that will not load for me. These are sites I regularly visited with no problems prior to using Tune-Up. The arrow at the top of my screen just keeps going in circles and the sites don't fully load.
I tried reverting to AVG default settings but that didn't help. I have another anti-virus software but disabling it didn't help either. My browser is Chrome version 59.0.3071.86.
