All this is very strange. From observations figured out if scan files without unpacking them, no viruses. If you unzip the files to scan and finds the two viruses.
Please, say it right: Two antiviruses states that they found two different viruses.
That's because these AVs don't find the viruses themself, but a module or sub that's associated with them... same goes for cgminer... if you scan cgminer, you get 28 different virus scanner detections.
There's still a good chance there's no virus in it at all.
