During a manual scan with my anti-virus Comodo on a jpeg file (a picture taken with a camera), it tells me that he has analyzed two objects. Should I conclude that there are 2 files in my image?
Did you also jpeg files containing 2 objects in one file? Is he may be a virus?
Cameras often store additional information (or metadata) for captured images. This information is often stored (depending on the Camera) in something called an Alternate Data Stream (or ADS). Now it is possible for a virus to hide in an ADS for an image file, which is why CIS scanned it and reported it as two objects (which, technically, it is).
