Avast is flagging several (but not all) JPG files as phishing. Website is hxtps://mybookcave.com. Seems to have started this morning. Why are those files flagged as phishing? They are book covers, nothing there that could make someone divulge confidential information. How do I get my website delisted?

CMS configuration issues: User Enumeration
The first two user ID’s were tested to determine if user enumeration is possible.

It is recommended to rename the admin user account to reduce the chance of brute force attacks occurring. As this will reduce the chance of automated password attackers gaining access. However it is important to understand that if the author archives are enabled it is usually possible to enumerate all users within a WordPress installation.

Thank you for those links. And for pointing out the user enumeration issue–I was not aware that this was even possible. I’ll be working on these as time permits.
Hello, my website is also having this same issue of muy clean site getting flagged all over the place for phishing by avast web shield. I have run multiple malware checks and wordfence cleanups and all looks ok.
The site is haciendaeltriangulo.com
Any suggestions? thank you.
First of all modify the link so it isn’t active (as I have in the quoted text) to avoid accidental exposure to a suspect site.
I don’t see anything about jpg files as the detection is on the domain, see attached image.

Woah! Was not expecting all of that. Thanks for the help, I’ll start trying to fix all of those issues one by one 
You’re welcome.
When you have some progress you can use this:
Reporting a Possible False Positive File or Website - https://www.avast.com/false-positive-file-form.php.
You should get a response in a day or two.
As and Avast user, I can only point you in the right direction, to remove it only the Avast virus labs team can do that.
Still flagged by avast’s,
