Hello Jeff,
Your site doesn't have a virus but the server your site is hosted on has been blacklisted due to other sites on the same box. Our systems firewall blocks access to any servers that have malicious content on them. You can see your site being blocked today here:
See Attached As to why our security has blocked your site you can see that your site which is hosted on the following IP Address has multiple blacklisted sites and malware on it.
https://www.virustotal.com/ru/ip-address/91.222.137.91/information/I would suggest switching to a reputable web host such as Siteground or Hostgator where you won't have to worry about other potentially harmful sites getting your site blacklisted. We cannot provide support on this currently as we cannot access your site or replicate this locally.
