I know this is not a site problem, but this seems like the best place to ask this question. Sometimes, when I try to download a font file, it seems to download, but the download breaks at the end and I get this message in the Tools/Downloads window of Firefox: "Blocked: May contain a virus or spyware." My OS is Windows 7 SP1. My antivirus is Malwarebytes. I really don't think there is a virus or spyware in the files because I see that many other people have downloaded them and not complained. Any suggestions?
