I'm at a loss as you have tried disabling the web shield and even with the web shield, I can access all of those areas.
If you have 6.0.1289 (and you still haven't confirmed that [you should include that in your signature]), then you can try the checking the avastUI, Real-Time Shields, Web Shield, Expert Settings, 'Scan traffic from well-known browser processes only.' Though I'm not to hopefully given you have tried disabling the web shield.
