I have tried basically all of the advice that I could find around here and elsewhere; Winsockfix did the trick a previous time when I had the same problem, but not this time; netsh winsock reset catalog; netsh int ip reset reset.log... all no use.
I have the following system software installed: Avast, Spybot, Glary Utilities, HD Tune, Registry Booster 2, SpeedupmyPC 2009 and Smart Defrag...
These are my IP settings:

Getting a little desperate after two full days of tinkering and rebooting with no result... Any suggestions very much appreciated!
