It's a false alarm, the program is fine and has no virus.
I'll make sure scancode sees this post and checks it out, and figures out what might be upsetting PrevX.
My antivirus tool (Eset nod32) doesn't see anything wrong with it, so i'm quite sure it's a false alarm; the designation of it as "high risk cloaked malware" by Prevx makes me suspicious that it's one of those "guesses" that these security programs do when they aren't really sure if anything is wrong.
When in doubt the best thing is to upload a file to an online scanner like VirusTotal (
http://www.virustotal.com/) and get a second opinion. I
did this for the Teddy installer, and basically everything said it was fine except for PrevX which said exactly what you described, which again makes me confident that what we have here is yet another case of a security program scaring people into thinking a program is dangerous just because the security program gets confused.
In practical terms, you can either add an exception to PrevX to make it ignore teddy, or you can go into PrevX options and look for some setting that tells PrevX to stop being so annoying and blocking programs that it is only guessing about.
