Hi wroot,
Many thanks for raising awareness about this and for running that support tool / sending the .sdbz file to Support. I have been working with Security Resposne to have a second look at these.
Security Response has confirmed that several of those .exe's are malicious: we classify them as Trojan.Gen and Trojan.Gen.2. Protection against these was added on 27 December 2012.
There were also some data files among the submissions: Symantec has not added any signatures against those as they are not capable of causing any harm in themselves. Feel free to delete them or they can be safely ignored.
The unicode2.nls (MD5 96b034bdf6c6f6c8cc64b70552f7656c) file from Tracking number #27534670 has been determined on second look to meet the criteria for detection: it is detected as Backdoor.Trojan from Sequence 140528 onward: those Rapid Release definitions are available now. This sequence appears in the SEP GUI as 1/2/2013 rev. 34, defs version 150102ah.
Here are details on how to download and apply those Rapid Release definitions now!

Cheers once again, wroot!
With thanks and best regards,
