The capitalisations of the file extension in itself might just be the reporting process, since there aren't two copies of explorer.(exe EXE) it is more likely a reporting hitch.

Are you experiencing any suspicious activity ?

You could also check the offending/suspect file at: VirusTotal - Multi engine on-line virus scanner
Or Jotti - Multi engine on-line virus scanner and report the results.
