Security issues and page opening

Hello, I have several websites, and occasionally I notice that when I click on a web page, another web site opens sometie porn website or some [[bad word removed]… This is most noticeable on Android devices. I’m using malware and vordfence plugin.

Can this be affected by NOT updated plug-ins? What is the best way for secure website?

Thank you
