I received an email from my hosting provider saying that this file was quarantined due to detected malware: /public_html/skin/Signedint.php Was this originally a magento file that carried some function? Can I just delete it or do I need to replace it with a clean file? If i have to replace it, where can I get another file? I jupgraded my magento to but still received the message that this file was corrupted. One of the AVs at virusTotal identified this file as CPR65E4.Webshell thanks

The file is indeed a malware. Here is a great list of commonly known vulnerabilities that can be found in Magento and WordPress.

Delete the file, change all passwords (admin, database, hosting), and ask the host to scan your Magento files one more time.

  • Deleted Signedint.php everywhere it was found. Also, found salesplug.php malware. All of themm seemed to be uploaded at the same time. Thanks

Also look in you var/package directory and you will find instance there. The malware will try to create the file again:

Here is the file I found added when I did git status on the site: Lib_Js_Int-

  • Thank you, Bro! Indeed there was Lib_Js_Int- Also, there is another pne: Salesplugin.php inside the sales directory in public_html. Another evidence is that when I upgraded my magento, those two files remained unchanged. Should I just delete those two forever?
