I wouldn't recommend using F-Secure SSH Client is it's deprecated. The developers don't offer any information about it anymore, therefore it shouldn't be used. I've tried to download it, but it appears there is no place to obtain it from, making it impossible to say exactly what function needs to be disable to avoid using hyperlink.
Instead of the F-Secure SSH Client, download and use Putty. Putty doesn't have hyperlinks activated and you can connect easily and securely to the servers.
