Today I've noticed that whenever I load a page on Digi, Avast reports that it has blocked a suspicious connection to chats.lulzsec.com (although the website itself still loads). The issue doesn't seem to be browser-specific (having tested it in both IE and Firefox) and I have yet to see this occur on any other websites. I had my brother test it on his PC and the alert still registered (albeit only after I logged my account in on his computer), but I am running a scan on my PC just in case there is something going on locally.

Is this something I should be concerned about? To anyone reading this topic, have you also recieved any alerts?
