Just a short note on the domain HIJACK-THIS.NET: this is not mine! It has been registered by XoftSpy (who are also on the Rogue Antispyware List on SpywareWarrior.com) and they are luring people into downloading their software believing it is HijackThis. Also, they have registered a few AdWords at Google leading to the same result. I have contacted them about this and received no reply (how surprising). Google can't do much about it since there is no copyright being breached. We'll see where this goes.
In the meantime, if you want to download any of my programs, the official domain is and always will be www.merijn.org.
