I’m still baffled trying to figure out what is causing this error. I ran clamscan so that the log file would be verbose. I’m including a few lines from the log on both sides of the error message. As far as I can see, it doesn’t give me a clue as to what file is causing the error:

I am only scanning my home directory, but I have many files which are much bigger than 25 MB, but only this one, unidentified file is causing the problem.

Please give me some explicit instructions on what I need to do to figure this out. Assume I know nothing, which is probably a valid assumption in this case.
