Hi Bob, I got your direct email with your answers. Here is what everyone need to understand about the problem you (and many others) are facing:
It is extremely easy for malware infections to spread from one site on your shared hosting server to another. There is nothing on your typical shared hosting server to stop a hacker’s script from copying itself all over your site and further to all the other sites on your account in just seconds. It even possible in many cases for the infection to spread out to (or from) another user’s account on that server.
Usually your hosting provider will take this opportunity to up-sell you to a VPS. While this option may improve you sites’ performance and usually prevents attack from crossing over from (or to) other users, it is not likely to stop any of the infection on any of your existing sites from spreading to all the other sites that are on this new VPS.
You said you have about 10 site on this shared hosting server and my plugin is on only 2 of them, but you think they are all infected. That simply won’t get your server clean. It is possible that you could get rid of this threat once and for all if you were able to coordinate your attack and completely clean all 10 sites at the same time, but the timing would be critical and it may take you several attempts to get them all clean at the same time with the infection spreading to the files you just cleaned. The best option is to move your site to a Super Secure Hosting provider ??
