I had kept getting resource overload messages and so I was slowly going through clearing out old domains. While I was doing so I noticed some php script in the home directory. I had no idea what it was. I checked my entry processes at the time and they were high and as soon as I deleted this php file they went back to 0. So I hadn't been having any issues with resource emails from my provider since then for 4 or 5 days but today I looked in my email and there was another message. So I look in the home folder and lo and behold yet another rogue php script and entry processes running high. Now I didn't change my password last time but this time I deleted the script and also changed my password. Will this be enough or do I have to take more measures. If so what?
