A year ago I wrote an article about what to do if your website has been hacked and recommended that you sign up for Sucuri. Sucuri will monitor your site on a scheduled basis, send you emails, tweets, text messages or instant messages when your site has been hacked or infected with malware, clean the site as many times as necessary in the course of the year you’ve paid for, and provide you with peace of mind. It is my most highly recommended service of all of the ones that I use.
Sucuri now has two WordPress plugins for subscribers and non-subscribers of their service. Both are useful and the one for subscribers has so many features that it’s yet another reason to start using Sucuri’s services.
