The file names shown in the quarantine window are as follows:
auto_.htaccess
deleteme.wplcyj.php
Oct-07-2014–17-16-32–auto_.htaccess
p3-profiler.php
deleteme.wpjytp.php
deleteme.wpgbpz.php
deleteme.wpogal.php
deleteme.wpeu2i.php
These are also shown in the appropriate bps-backup/quarantine folder for the site. I have viewed them and there is definitely a lot of content in each. Fortunately I can now see what they represent in terms of their origin – the deleteme files are from Installatron which is a bit of software used by my web host. The auto_.htaccess files are not blank in my case.
So, I am stumped! If I can help further with anything then do let me know. Whilst I can now at least check the files via FTP, there does seem to be a bug?
Thanks
