Hi! I heard of a good virus scanner for linux called Clamscan, but dnf cannot find the repo and neither does apt-get. Anyone know how to get this scanner, or another good scanner? I has always been told that linux does not have viruses, but i guess it must since they have released a virus scanner. Also, how do i protect my workstation agains DdOs attacs?

I believe you have heard few different things but aren't sure how to interpret them. :-)

Every platform has viruses and every platform is vulnerable, some less some more. That said do you need antivirus on Linux? Well, that depends on your use case. Anti malware software that you can find on Windows platform is generally different that ClamAV or maldet on linux are.

To install ClamAV you can use:

sudo dnf install clamav.x86_64

I have never used antivirus software on my desktop computers because there is no need to do so. For malware to be successful it needs to be executed somehow and on Fedora most of the ways to do that are really well mitigated. Besides sane default program configuration Fedora also uses SELinux, a mechanism that independently decides if some program should be allowed, write, read or execute access to some other file.

That said, I have used anti virus on the servers but again, not for the purpose to protect them (that needs to be done by secure configuration, isolation of users etc.) but for the purpose of detecting files that have been injected into websites. Many popular website systems are exploited if they aren't patched regularly and many website owners don't do that :-)

Regarding your question about DDoS attacks, I am not quite sure what do you mean by that but I would first suggest that you read this article about Denial-of-service to better understand this topic. Have you experienced those kinds of attacks to your workstation/home network? If so, your ISP should do the work to protect you against those kinds of attacks.
