I actually found the malware calling itself "chromium" to be funny, because if your creating malware and you want it to look like chrome...why not just call it chrome? Are they afraid of getting sued? It's malware!
But I think the reason they did it is so when people google "is chromium a safe browser" it comes up with legit sites. But even that strikes me as odd, because who is seeing browsers just mysteriously install on their PC and then google it and see it's "safe" and just shrug it off. That's like coming home to your house having a extra lock on your door. If your key could still unlock it would you shrug it off to magic carpenter fairies? No...yet people do that with computers. It blows my mind.
