Anti-Virus Update Fails After 5%

Today, every time I try to update the anti-virus database, it reaches 5%, and then I get a message saying the update failed, please check my internet connection. My internet connection is working perfectly, and no other network application is affected.

What should I do?

What version of CIS are you using? When using an older version of CIS, uninstall it and update to the latest version: Free Firewall - Download the Best Firewall Protection and Anti-Virus Scan Software from Comodo .

I was using the latest Comodo version. The problem solved itself later that day. Thanks for your reply.
