I have been having issues lately with a certain directory. It seems someone is placing files into it, or something of that sort, and any attempt to delete them is successful, HOWEVER they reappear over time (maybe not the exact same ones, but random files).

I will provide you the information I can and several pictures of my problem:


sandbox.mys4l.com/visual/files/b1.jpg Files like this have been appearing in my /visual/ folder, and I have no clue where they are coming from.

sandbox.mys4l.com/visual/files/b2.jpg This is what is inside on of those weird files, it appears to be nothing problematic.

sandbox.mys4l.com/visual/files/b4.jpg As you can see, in the time it took me to take the first picture, more odd files showed up. These log files are also being uploaded to this directory, and I know I didn't put them there.

sandbox.mys4l.com/visual/files/b7.jpg This inside one of these mysterious .log files, I'm not sure what it's all about.


These files only appear to be going into this specific area, and I'm not sure of their origin, only that they will not go away. I have done a full system scan at least twice with an up-to-date virus scan, and have looked for an unknown script which may be writing them there. Nothing has come up, so I come to you guys as I hear this is the best place to find answers.

Hope this problem has a solution!
