I posted a similar question here about some coins I was interested in. I will be following your thread, you may want to check my thread as well.
https://bitcointalk.org/index.php?topic=2750281.0One thing I will say is that any wallet I do download, before I even open it, I upload it to virustotal.com to see what its report says. I have read that because some real malware uses miner like functionality, that you sometimes get false positives. I still don't have a definitive way of determining which wallets are safe vs. those that are not, especially for more obscure altcoins.
