Hi Norman ,
Thanks for reaching out. Sorry you’re having to deal with this. The issue is with the “AVG Web Shield” being active on our site. We have thousands of customers that take use our Cloud WordPress services domain and at some point AVG flagged one of those domains as suspicious and it happened to effect all domains being hosted on their platform.
You could deactivate the security plugin and that should resolve the issue or you may be able to reach out to AVG directly and have them to add your URL to their whitelist.
I hope this helps. Please reach back out to us if you have any other questions or concerns.
