Virus - Suspicious.AD

Unless you have jailbroken/hacked your iPhone, nothing can be installed on an iPhone from a received email, from a website, or from a received MMS except for a photo which must be done manually, and I haven't read any reports about malware being included with a JPEG file.

"Suspicious.AD is a highly sensitive detection technology designed to detect new malware threats without utilizing the traditional signatures. Files detected as Suspicious.AD indicates that it has suspicious characteristics and may contain an unknown threat.
Damage Level: Low
Systems Affected: Windows"

Maybe you got a virus on an image you downloaded from somewhere and inserted on your iPhone's photo roll?

Anyways, it will 'only' affect windows. I somehow doubt your anti-virus can quarantine the files inside the iPhone, so that's why you get repeated quarantines. Furthermore, from the text above, it is only a probability of being a virus, it may or may not be one.

Anyways, what exactly are you using to sync, and did you buy the iPhone from a reliable source? If it is jailbroken, there could be other issues...

Maybe you got a virus on an image you downloaded from somewhere and inserted on your iPhone's photo roll?

I've never read any reports about malware or a Windows virus being included with a JPEG or image type file. Can you provide any links that support malware or a Windows virus being included with such a file?

Yeah, you're right, I don't think it can actually have a virus, they are actually .exe files, and only Windows can be 'tricked' into confusing an .exe as a JPEG. My mistake there. I don't see how the iPhone would be dupped like that.

So maybe it's just the anti-virus looking at a file, and thinking there might be a virus.

What anti-virus is the OP using?

edit: regarding jpeg viruses:

Didn't quite understand if that report had something to do with dupping windows to think it was a jpeg file, or if it was really a jpeg, that took advantage of some vulnerability when reading the file (hovering with the mouse accesses at least the metadata)

edit2: also, sophos has previously showed you can have JPEGS that execute code, but you'd first have to have 'installed' a virus (.exe file), that will then run the code present on the JPEG file. So you'd have to be infected first. Maybe he has such an image? (speculating is fun!)
