Webroot Caution on my site on google search

Hi

When googling my website (certainly via Microsoft Edge) a yellow Webroot Caution is displayed, warning users of potentially unsafe content that can affect their online security.

Where do I start looking to solve the issue?

Thanks, website below if there's anything blatant.

You could start by checking your website's source code for any malicious or unwanted content. It's also a good idea to scan your website with an online scanner or security software. You could also review your website's logs for any messages that may indicate the source of the issue.
