I don't think it's a virus, I think the build config is putting 0.5.3 in there when it's really 0.5.2. I didn't get updated but Windows thinks there's a virus in here, for some reason, when I don't think there is, given the SHA 256 checks out. It's the installer you produced.
the 256-SHA hash is correct but it says this:
Subject: Gossip 0.5.3 Installer
