Is Your WordPress Website Secure?

I receive an alarming number of calls regarding WordPress intrusions. Some of the people who contact me are aware they’ve been hacked, while others have only noticed that their website is loading slowly or having other minor glitches. Sometimes evidence that your WordPress website has been hacked is prominent — there’s an advertisement for Viagra or Ugg Boots right on your homepage. Other times, however, your website may not show any signs of the hack at all.
