Which software wallets are safe?

So, continuing with my newbie mining adventure, I'm looking at other hot coins to mine such as ZClassic and GoByte. With that, I have to wonder which wallets are safe to install on my computer, especially as coins become more obscure / less main stream. I've heard of lesser known wallets that actually contain malware / viruses. So besides uploading the wallet to VirusTotal for scanning, I wanted to reach out to this community to ask if they have experience with the following coins and which wallets they feel are safe for the coins.

Also, I know keeping the computer itself free of viruses and malware is of paramount importance... I just want to make sure none of the wallets I download are malicious.

Here's what I'm looking at right now:

ZClassic
Trezacoin
GoByte

Thanks,
