I've been trying to help my mother in law to backup / upgrade her old Mac. In order to use online backup solutions, I've had to transfer her files to my Windows PC. As files were transferring, I saw a couple suspect .exe's caught by my bitdefender antivirus (thankfully!). They were "lcodecplus.exe" and "update.exe" My question is:
As this Mac had these files on it, is it possible that the malicious code ran on the mac, and now my Windows PC is infected from the transfer? Or should I stop being paranoid, considering the antivirus caught them?
From my research, it sounds like it's unlikely a virus for one platform to be executed on another. I'm hoping that as bitdefender caught them on the way in, I'm at no more risk than I have already been, but should I be concerned?
