Hi Laranz,
Thank you for your reply. I had to act quickly for obvious reasons and so after speaking with my hosting company, I deleted the site from FTP again, re-uploaded and via a new install WordPress and of the Wordfence plugin, managed to isolate and delete the malware code.
All seems to be working fine now and am scanning daily. Are there any other tips for preventing this kind of intrusion in the future?
Many thanks,
P.s. On a different subject, what is the multi-directional background you now have on the swiftideas home page and can this plugin be implemented into my Neighborhood theme?.. Would love to have that effect as a slider!
