Avast keeps blocking my websites

Hello,

I have a couple of websites running on an Apache webserver; all of them have been blocked by Avast, and I couldn’t realize the reason why.
The websites are:

Things I’ve done so far:

  • Check some blacklist services;
  • Install a SSL certificate on the first website above using LetsEncrypt;
  • Remove some files [some images (.jpg), Javascripts, CSS] Avast accused as bad.

None of these solved the problem.

Some pictures of the captured errors:

Could anyone help me, please?

Did you add an exclusion in web shield?

I do not see it blocked by avast’s…http://toolbar.netcraft.com/site_report?url=https://oceanografiaoperacional.net
