I remember that Hitman Pro once flagged Bitcoin Core as unsafe because it contained a trojan virus according to the report, but it was a false positive. Not sure why they keep flagging crypto related clients falsely, but it's nothing to worry about.
https://www.virustotal.com/ is a handy site allowing you to see how a wide variety of anti virus software brands react to whatever you try to screen. Some will flag it falsely, but most will not react at all.
When it comes to trading I have never been a fan of using whatever software based client since I am too paranoid about potential flaws and whatnot. It's always much safer to access the site itself. The less you have to install the better.
