Yeah the article really didnt explain it at all. I sure as hell hope I dont have it.
The article suggested to make sure that - if you're running Windows - to make sure that you have all of the available patches and updates for it.
The updates, from what I read, will prevent this virus/trojan. And if you already have it, it will stop its activity. Of course from there, then your anti-virus should be able to detect it.
When it comes to anti-virus, I would highly recommend using McAfee. It's very affordable, frequently updated, and definitely one of the best ones available. Most-importantly, being commercial, it's always being improved. One important thing I must stress out with
McAfee is that it's not a resource hog, which many users claim it to be.
And, for your own convenience in relation to McAfee anti-virus, you can buy it very inexpensively online at Buy.com:
McAfee Total Protection 2009: 3-user; the product I just linked to is only $14.99 for one year of exceptional anti-virus protection, detection, and prevention, including a lot of many interesting features such as its phenomenal firewall (which I researched is actually better than ZoneAlarm and is very comparable, if not better, than ZoneAlarm Pro), AND is valid for use on up to three computers. You really can't go wrong with McAfee, especially at that price!
