I am going to try and attempt to explained what happened. Early this morning, I got a call from my webmaster/development company saying that my site was hacked sending out trojans and if some was to go to a page on the site it would redirect them to a malicious site. In total they found ten files placed into the server sending out spam and redirects. I have no idea how to do this. At the same time this was going on the rankings for the site plummeted to nowhere to be found?
I am trying to get a straight answer out of someone that may be versed in this area of having your server infected and doing this? It was hosted on a dedicated server, now I have to change the hosting because they think believe I infected so many others servers, etc, which I don't understand how that happens either. Is there anyone, expert, that is versed in how to recover from this and what to do to prevent this from happening in the future?
