Yoast news SEO null safe?

My web recently got approved by Google news so I wanted to improve my visibliity in Google news, upon googling I found out that yoast news SEO can help me.
Although I found the nulled version of this plugin on a forum and it was verified as safe using virustotal.com
Soooo should I proceed and install this plugin or no? Will it effect my SEO? Is yoast news SEO worth the risk?

Nulled version have a redirect module and shit you don't really need. Install the free version and a redirect plugin and stay safe.
