I just started using Ubuntu 18.04.1 version and two days ago , I received an email from trusted source with 2 attachments and I downloaded those files on my desktop, files were encrypted and were asking me to sign in with my passwords to open, I tried to open those files as well. Later on I found out that sender's server was hacked and that email was from hackers.

Then I installed ClamTK anti virus and run scan today and found out below results. These are just a small sample, I have hundreds of these output in my terminal. What is this? is this normal or its a virus? many thanks

Known viruses refers to the number of viruses in the clamav signature database (ie. viruses that it can scan for or knows about).

ClamAV scanned 337081 files in your 59238 directories & found 0 infected files (using the 6752421 viruses it knows about that were looked for) This is a good result :)
