I have changed all pws, checked for ftp accounts, made sure I had no external mysql connections, rebuilt the parsed templates to make sure they had no malicious code. Checked for base64 in both templates and plugins.
CHMOD all folders to 644 unless needed for users (like avatars), those that are 777 write-able have .htaccess files protecting them from executing php.
Checked all plugins (all are known to me). Deleted ones that I didn't use or didn't trust.
Had my host scan for viruses.
VBSEO is 3.5.2, not current version.
And yet... every few hours it comes back.
I am not blaming VBSEO, but their staff has helped in the past, so I am posting here.
Can anyone help?
