Malware on FTH website?

One of my members just sent me this screenshot. 
The problem is I can reach the site just fine from a different location.
6193.toastmastersclubs.org/
Not sure what I can do. 
Thanks for your help.

How did your member try accessing the site?  
A similar error shows with old links that don't have the secure https protocol embedded in them (although the warning is usually 'this site is not secure' rather than a malware warning)
Check if they have clicked on a 'bad' link instead of   

It must have been a glitch. It's working fine now.
BTW, the person was accessing the URL tm6193.org which is forwarded to FTH. So there wasn't an issue of whether they were accessing the site without the https://

But thank you for your reply.
All the best,
Michelle

You domain is not set up properly.

FTH does not support domain forwarding.

Please read the correct domain settings in the documentation.
