Your website is blacklisted because Google scanned your site and found harmful behavior. Google needs to protect its users from dangerous websites that show up in their search results. In fact, websites that repeatedly get blacklisted for malicious behavior are limited to only one review every 30 days. That big red splash page (and warnings next to your site in Google's search results) are designed to stop visitors from entering your site. It works, too. Websites lose about 95% of their traffic when blacklisted by Google.

It is important for a company to identify website security warnings. Check how many backlinks you have and from which sites you are getting those backlinks, If those sites are not relevant to your niche or are banned then it might be the case that your site also gets blacklisted. At that time you may use disavow code to stop the search engines from calculating backlinks from those banned sites.
