Avast blocking websites with no notification or logging

For the past few days I’ve been having sporadic problems with loading websites or web page elements. Either the page load will time out with a connection reset error, or images will come up as broken links. If I disable Avast’s shields then the pages load normally. There are no messages from Avast that it’s blocking anything and nothing out of the ordinary is shown in the logs. Pretty irritating. Using 7.0.1426.

have you just installed avast ?
what AV did you have before avast ?
any other security programs installed ?
firewall…what ?

Been using Avast since April '10. This particular machine was a clean install done in January of this year. No other AV or firewall programs are installed, or have been installed on it. First started noticing the problem after the update to v. 7.
