Spyware, viruses, & security : Alternate Data Streams: Naughty Pirates

Alternate Data Streams: Naughty Pirates

I am using an explorer replacement tool that I absolutely love. The problem is that last October, I ran ADS Spy and it alerted me that the license key file it uses contained an alternate data stream identified as "naughty pirates." After running the cleaner, the problem seemed to be resolved, but in running it over this past week, after 2 updates to the program, it is absolutely back. The developer of the explorer replacement is assuring me that the ADS is nothing to be concerned about.

In explorer, the file size changes, but is typically around 712 kb. In ADS Spy, the actual size is reported as 2800 kb.

Is there a way to verify the safety of this file outside of ADS Spy to confirm or refute it comes bundled with spyware?
Thanks
