It looks to be genuine but if they can create a malicious program that appears to be the Adobe Reader, I'm sure they can make the "about" contents say whatever they want. Where did you download it from?
If you are in doubt for some reason, uninstall then get the certified version from http://get.adobe.com/reader/
I got it put when windows was installed.
I've heard we cant uninstall malicious programs, thier uninstall.exe's are made malicious. I mean they will not completely uninstall it or will introduce further malicious stuff.
