Windows XP-SP3, Avast Free today updated to 8.0.1489 over the .1483 (not clean install), definitions 130613-1 are current.
Since the update with enabled Web shield I can no longer get out to the internet using Opera or SeaMonkey.
I can ping google from cmd.
Disabled Webshield seems to be the only solution to be able to come here or Wilders or other safe places.
