Linux a little help install issue

so I been trying to download linux, but it comes in a zip file, once installed. I noticed 7zip was recommended to convert it but when i ran 7zip or winrar in Virustotal is showed up as a malware cynet score 100. I dont know if it was a false positive .
So now I am stuck on not being able to download linux to install. any ideas? help? next thought was vmware then install Ubuntu. recommendations appreciated
