icedragon_updater.exe doesn't have signature?


As the topic says, icedragon_updater.exe doesn’t seem to be signed (tried with SigCheck). Why is this? Also when uploading it to Valkyrie and copy pasting its SHA1 in Comodo File Intelligence, the verdict for the file is “unknown”. Shouldn’t it detect it as safe, considering it’s Comodo’s own file? Just wondering if I have a corrupt file here or something.

PS. this seems to apply for restart_helper.exe as well.
