Getting hacked sucks, plain and simple. It can affect your rankings, cause your readership to be exposed to virus and trojan attacks, make you an unwilling promoter to subject material you may not actually endorse, and in many cases cause the loss of valuable content. However, once it happens it is usually best to not procrastinate on the clean up process, since a speedy restore will most times minimize the damage that was caused.

While almost all sources will recommend that you upgrade your WordPress to the latest version, what the majority neglect to tell you is that in most cases simply doing so will not prevent the attackers from getting back in, even if there are no known exploits with the latest version. The hackers may have left a back door file hidden in a directory where it wouldn't get overwritten with an upgrade, or inserted code into your theme, or simply created an account that they then granted admin privileges to. Any one of those would allow them back in, even after you patched what was wrong the first time. Therefore I am providing this step by step process on how to completely clean out and restore a WordPress installation that has been hacked.
