Do I REALLY have a virus or malware?

[MarkTiede]

I just got a NAS. I copied some files to it. Then I ran an antivirus program from the NAS and scanned the files and I got 3 hits (so far).


I got


Win.Virus.Sality-6822589-0

Win.Trojan.Badjoke-7


Microsoft Security Intelligence says that Defender detects Win/Sality, but when I scan the file on the PC, it says it is okay.


Is this a case of a false positive or is this a new version that Defender doesn't know about. (All the defender updates have been applied)


Same thing for the Win.Trojan.Badjoke-7?


Or is the NAS antivirus program just better at finding these?
