Just a note for everyone: This newportalse.com hack was definitely a hack that coincided with the timthumb.php vulnerability, which was discovered in early August.
I had updated that plugin/cleaned out the malware from the files that was recommended, but the newportalse.com flag in Chrome was still happening.
For those of you who came to this problem via the newportalse.com hack, you also need to go back and check for several other files in your WordPress installation.
Excellent details of how to do that are found here: https://techspheria.com/2011/08/phpremoteview-hack-what-it-is-and-how-to-remove-it/
I’d be interested if anyone continues to get flags for this hack after dealing with the Javascript file mentioned. Good luck folks.
