It seems clean: https://www.virustotal.com/en/file/8ace4ca8e987d8e414c8d90987bf4d059451748ab3d0fe07a0cbd695fc0a7777/analysis/ (the few positives are most likely false positives)
The MD5 checksum is also the same as the one from the reddcoin-qt I downloaded from the official link a while ago. So the download provided seems to be clean and you could use it.

The wallet could also probably be downloaded from https://github.com/reddcoin/reddcoin and you could compile it yourself.
