Hi, Felipe !
I regularly use VirusTotal (if it's available, that is, seems to be very busy lately) and have noticed before that
Jiangmin seems to dislike 7-zipped self extractors with a UPX compressed executable in it ...
Just unpack the self extractor with 7-zip
and scan the separate
parts, if you're worried -
how many Trojans do you know that are delivered with source code
You could also just download the latest exiftool
replace the one used in CameraVersion 1.1
hope that helps,
PS just scanned it with Jotti
(VT was overloaded again) and it found nothing
