The GotMLS WordPress plugin scanned and informed me that index.php was infected and needed to be quarantined. However, this file keeps reappearing and is now in quarantine 9 times. I deleted this file in Cpanel using FileManager but it keeps coming back. Is this file really infected?
I would guess that it really was infected. It is common to be repeatedly reinfected in the same way using the same exploit that allowed you to be infected in the first place. In fact I can see some spam scripts in the headers of your site but it looks like you have removed my plugin so I’m not sure how I can help you with this.
If you would like to reinstall my plugin and give it another try then I might be able to provide you with some guidance that could help you resolve this issue for good.
