CWIS Blacklist Monitoring scanner checks IP addresses and website domains in most popular blacklists and safe browsing databases. Real-time Blacklists or Blackhole lists – also called DNS-based Blackhole Lists – are lists of IP addresses published through DNS. Often there are listed computers or networks that may spam or consist malware in such lists. Many secure corporate mail servers are configured to reject or flag messages which have been sent from IP addresses listed in one of these blacklists.

Leading email systems like Gmail, Yahoo and Hotmail also use blacklists to filter emails by addresses. If your network’s IP addresses end up in a blacklist, you and your customers can experience problems sending and receiving emails. It can significantly damage your business.

CWIS Blacklist Monitoring scanner will automatically alert you if your website addresses or domains become listed in any of the widely used URL blacklists.

URIBL (or URL Blacklists) are similar to RBLs, except rather than tracking IP addresses they track domain names and website URLs which have been identified as being used for spamming, phishing or spreading viruses.

If your website becomes blacklisted, any reference to your website URL may be blocked, including:

  • referencing your website URL in email;
  • social media or blog posts;
  • or visitors simply will not be able to get to your website.

The Google and Yandex Safe Browsing databases include lists of websites that may be dangerous to visitors because they are suspected of phishing scams or spreading viruses.



The CWIS Antivirus Security Scanner will not only help you find all of the viruses and malicious code on your web site but we will also help you remove this malware easily. Our built-in file viewer and editor is an easy tool to remove the infected file code or its part depending on the type of infection.
