One of the most common problems that we observe among many of our clients is the persistent threat of cross contamination – that is, malware that spreads from one website to another when they are hosted in the same environment. This is particularly common within cPanel environments when add-on domains are used, or within improperly configured Virtual Private Servers (VPS). While we have been warning clients about the risks posed by cross contamination for many years, we haven’t yet produced any content instructing website owners on exactly how to avoid it.
