However, 2 weeks ago random ads started showing up after searching on Google. I just ignored them at the time but when I went to create a WordPress Post I came across a random image icon in the Visual editor display.
On removing the appspector extension it automatically opened up another tab which tried to tell me that my flash player was out of date and started downloading a new version. No doubt If I installed it would lead to many viruses.
How Widespread is it?
Having checked all of my WordPress posts and pages including drafts I only encountered it on my last published post and my projects page which I updated the same day. All posts prior to this were fine. However, I am not certain if this affects users using other Content Management Systems like Drupal or Joomla.

Remember to save your post! Come across any other CMS that has been affected by the Appspector XSS injection? Please feel free to have your say.
