I tested this successfully with SMC.URL and SymantecAntivirus.lnk. Both show as Detected. However, when I try "Symantec Antivirus.lnk", it fails. "SymantecAntivirus.lnk" also fails.
I would submit this issue to Symantec support, as this appears to be a bug. I only tested the *Desktop selection with .URL and .LNK files on my desktop. .URL and .LNK behave identically; anything with quotes fails; anything with a space fails.
