I have a website that have been attacked with malware in the past.
I cleaned all the malware and the site is working properly, however, every day I check the site and find new files added under the "pomo" library.
As far as I know the pomo library is supposed to contain 5 files, in this site there are 6, but when deleting the 6th file the website doesn't show, I suppose that the additional file may have been added by the template, in any case, I had it checked and it doesn't contains any malware
the file name is "adodb.class.php" and in comments introduction it says:
