I deployed a website on a server at home and it will run fine for a few days, however it will change over to a directory browsing typ (FTP) looking site, ive noticed that PHP and some program callded we developer is installed. and i cant browse my site anymore. i have deleted these directories and then it works fine for a couple of days, then it happens again. I have done this about 3 times allready and now am unable to even RDP into it. so I just had the kid shut the whole server down. I am using Clam antivirus and linksys fire wall.
Is there anyway to tell when this thing hijacks my server? and how do i stop it?
