Adobe Flash updates are already an attack vector for some malware. My wife was presented with a "FlashPlus" installer to "update to the latest version of Flash" that looked exactly like Adobe's with the exception of the name. I'm still not sure what good fortune intervened to show me that particular installer before she hit "install".
I wonder why the creators of such an installer even bothered changing the name? Virus/malware authors shouldn't care about the possibility of trademark violations; They usually take care to ensure the software can't be traced back to their identities regardless.
