Basically: If you used this in conjunction with an account, check all your stuff, remove any info from your account (or terminate it) and cease use of TeamViewer immediately. If you only ever used the connect-by-numbers thing, you have nothing to worry about.

Kind of a huge shocker to me, since my dad and I use it every so often (without an account, thankfully) and one of the companies we do stuff for has a TeamViewer client set up in a personalized way. I hope they don't get affected by this.

No bueno. I've always been a little wary of remote desktop thingies for this very reason - they can be a very dangerous attack vector. I've never used TeamViewer, but thanks for the heads up.
