This is not a solution, just sharing my experience-
Over two months worth of posts have disappeared from the web site. I have downloaded the XML file of posts and discovered that the missing posts were still in the file but that everyone had been infected with spam. The spam is in the form of hidden links to porn sites. I went through the file and deleted all the spam and then uploaded the file back to WordPress using the import posts utility. I thought that this might clear out the infected files by replacing them but this does not seem to have worked. By looking at the comment id, I can still load up the infected files. The porn links of course aren’t visible in normal view but if I view the source, they still appear. I would like – a) to get rid of the infected links and b) to replace the fifty or so posts with the cleaned up version without spending hours and hours in the process. The version of WordPress I am now using is 2.5.
