Here's what part of the article--and system security outfit, Panda Software--says:

Panda's advisory last week revealed that the 100KB file is in fact adware, which "downloads and runs files, changes the DNS configuration and monitors accesses to several adult websites". zCodec, formally known as Adware/ZCodec or Adware/EMediacodec, affects most versions of Windows and was first detected last week, Panda said.
When run, the program alters the system's DNS configuration in order to divert traffic to DNS servers of its choice, a technique sometimes used as part of a phishing scam or to rack up clicks for advertising schemes.
zCodec also accesses a particular IP address to randomly select and download one of a collection of files. The files that could be downloaded include Ruins.MB, a Trojan horse that uses rootkit techniques to conceal itself, Panda said. zCodec could also download an online casino program.
A second file launches every time the user starts Internet Explorer and monitors Web usage. Panda said its software can remove zCodec.

So, chances are that second file wouldn't run if you use Firefox or Opera, but the rest of zCodec is disturbing, especially since the program (and website) passes itself off as a freely legal and safe download.

Anyway, that's about it. I saw this and thought that everyone here should be alerted about this program. I figure most everyone here keeps pretty safe Internet habits, so perhaps this warning wasn't even really necessary. Regardless, I felt it'd be good to have here.
