Some common security practices to protect yourselves, even from a zero day like this, is to only run under a limited user account and not as an administrator. Go into control panel, make sure everyone who uses this pc has a user account, make sure each user account is limited, and set a good password on the administrator account that you can use to install needed software, and install software only. Also, make sure your firewall is on, if you use a router you should be okay behind it, as it is a hardware firewall, always make sure you have anti virus software and anti spyware software, here is a page full of free scans for your system, use them as many times as you like.
Don’t accept files from people you don’t know, if you get a suspicious file from someone you do trust, ask them what it is before opening, they could be infected and actually spreading malware, there are many cases of that happening, IM Worm Attack Cloaked in Virtual Card Hoax, Spim, Splog and Spam On the Rise and here is a list of the Latest IM and P2P Threats for your perusal. Oh, and I know some people won’t like this, but, always, allow Windows to download the latest patches, you don’t have to let them do it by itself, but at least download and look through the list.
