WS.Reputation.1 false positive (qemu-img.exe)

I downloaded QEMU and tried to create a virtual machine. However, when I try, it says that qemu-img.exe has been removed due to WS.Reputation.1 threat. I tried to restore the file but I can't as Quarantine is stuck in loading, and as such I can't use the program nor report a false positive. Any ideas?
