there are, there are just fewer because less people use linux, so less people make viruses for it. that, and linux has the capability to be a lot safer if you control all the aspects of it.
Think about it — If your ultimate goal is to maximize the chance of infection, would you target the 90% Windows users or the mere 3% Linux users? Source: https://www.netmarketshare.com/operating-system-market-share.aspx?qprid=10&qpcustomd=0
Who told you Linux has no virus?
@Ahri Fox if it was true, Linux should be primary target of Malware infection, because more than 80% high end servers run on Linux today. And by the way Android is a Linux based, so now probably there are more Linux devices on Earth than Windows. @Ahri Fox wrote: "there are, there are just fewer because less people use linux, so less people make viruses for it. that, and linux has the capability to be a lot safer if you control all the aspects of it."
And 60% of mobile devices are based on Android which is Linux based, according to your link https://www.netmarketshare.com/operating-system-market-share.aspx?qprid=10&qpcustomd=0 "Google claims over 2 billion users with Android while Microsoft has claimed over 1.4 billion users for Windows." https://en.m.wikipedia.org/wiki/Usage_share_of_operating_systems Unix-like servers (Where is Linux too) runs 70 - 98% of public servers. So if you would be hacker would you target 70% of servers and 60% of mobile devices in the world? which is at least about 50% of all OS devices.

I found the link https://en.m.wikipedia.org/wiki/Linux_malware there is the ANSWER... so my question is kind of silly. Hope for those like me it will be helpful. and Thanks everybody for your attention and answers!
just like windows linux too have viruses but think that if a attacker wants to target more people would they make virus for mac or linux which have far less users than windows.
