Antivirus

Hi all, I have downloaded the Faces pack, and all is well with the game, but when I do a full system virus scan, it gets so far then gets stuck on a .DS_Store file within the faces folders…any idea what is going on? 

I can't even find the file (and have no idea what it is)

When I deleted the whole faces folder the scan completed with no issues

Not a massive problem, but one that I could do with some help if possible?
Many thanks
