Is anyone else having issues with Google Chrome flaking out on them?

Several times a day mine will suddenly not be able to connect although the Internet connexion is up and I can connect through Firefox (usually). I'm talking about a desktop that is connected via wires. Resetting the router works, but should be unnecessary, as it is obviously connected already. Any ideas? I'm using AVG Internet Security as well. Could that be an issue? Thanks for any suggestions...I really do prefer Chrome as my default browser, although Firefox has definite good points. (I really don't care for Internet Explorer, however, and mainly use it to download other browsers.)
