http://cbl.abuseat.org/lookup.cgi?ip=**.**.** I got blocked from a website saying that my IP was blacklisted. Waledac is a Windows worm thingy. I haven't even booted into Windows from my computer in at least a day. There's another Windows computer on the network but I also doubt that it's infected (automatically downloads the latest updates, running EMET.) Strange. Thoughts? edit: Perhaps this is linked to OpenDNS, which I switched to yesterday.
