I upgraded to avast! 9.0.1500 on October 21. I do not recall upgrading since then but see I am now running 9.0.2006. This morning IE10 took 90 seconds to load pages. I would often get ‘The webpage is not responding’, forcing an IE restart. I can confirm that disabling the avast! Online Security add-on made the problem go away. I have opened ticket #DZD-803-34187 with avast!.
