Unknown File

Today I ran an analysis with ESET mobile, and it gives me a result:

File analyzed .KY0yZI no thread found

What is .KY0yZI?

Probably it didn't come from ESET. After installing an application, ESET's notification reads "App scanned". A screen shot will be needed for clarification.

Same thing happened to me, downloaded a pdf and eset scanned both that and a weirdly named file. Can't find where it came from and would also like to know what it is.
