Harmful urls are being added to my index.php file, which is getting Google to mark my sites as harmful.
But as fast as I fix them they're added again. Hosting company says my FTP passwords may have been compromised, but I keep changing them and still I get hacked.
There are 3 different hosting companies involved, so the only thing common is my PC, but I've bought a new PC, got MS Security Essentials running, have done Malwarebytes AntwMalware and Spybot.
Which plugin is most likely to secure things for me, please?
I'm very non-technical and came to WordPress because of that, so this is a nightmare for me.
Hope someone can help. Please!
