Hello Patricia and thanks for reaching us.
Andrea here from Themes2go Customer Support and I’ll support you with your request.

From what I read, I’m almost sure you’re website has been infected by a malware (file wp-tmp.php is not part of our product, it’s been generated from the malware)
Our theme has been modified by the malware and the antivirus has been triggered.

An easy fix could be this:
– download the theme from Themeforest (https://themeforest.net/downloads)
– via FTP, upload the updated theme to your server and erase the old one.
– Access to your backend and install Wordfence (https://wordpress.org/plugins/wordfence/) and scan your website looking for malwares and errors. If present, Wordfence will help you with its removal.

Hope this helps you.
Keep me posted.

Andrea

Hello Patricia,
in your previous action, did you replace the entire theme folder + child theme?
This because I ran Wordfence on our online demo and no error came up, so I think there are still some infected files on your website.

Wordfence can’t delete wp-admin files, but you can replace them via FTP and no warning should come up again.

Please, keep me posted on this.
If the problem persists, I will make this topic private so you can share your website credentials and I will check it for you.

Andrea
