Is Linux a solution for Ransomware and malware?

There are a few choices for operating systems for PCs.  You have the Microsoft  Windows camp.  And then you have my favorite – Linux with its many distributions.   My claim is that to avoid malicious software like viruses and rootkits, Linux is the answer.   From what I’ve read, Linux is more secure than Microsoft Windows because it was designed  from the ground up with security in mind.
