Hello, All of my clients are getting malicious emails sent from my server. I have never dealt with anything like this, I already contacted them adn explained the situation. One of them is infected and can't use his computer anymore. It is about a debian 7 perfect ispconfig server with apache from the tutorials. What are the apropriate steps? I already have a new server spinned up to move everything, but I don't want it getting infected as well. I am literally panicking... Thanks.
