Is it your anti-virus saying that? If so, can you give me the name of your anti-virus. I will contact them about the dangers of false-positives. P.S. Yes it's safe, but you may want to wait for a non-owner to tell you that.
Yes, Runemate is safe to use. No viruses. I highly advise you set up your Two Factor Authentication for your Runemate account login for added security. The staff here at Runemate have gone out of their way to make security #1 priority. Tutorial here: https://www.runemate.com/community/threads/introducing-two-factor-authentication.849/#post-5886
