I did try to do some digging, not sure exactly where the cause is, but when I check through the developer tools of chrome it appears the redirect somehow originates from plugins folder, at least I see one of the offending urls in that context during page load.
I would advice to remove all plugins and make sure you reinstall with fresh files. If that doesnt help, fresh files for the full wordpress installation might be needed. To achieve this delete everything except wp_config.php (make sure it looks clean, compare with a fresh one if needed), take a backup of your uploaded photos and other files you did upload as part of the contents, make sure you know each and every file is yours and clean.
All posts and settings are in the database, so you should not loose any of that in the process. Also make sure all plugins as well as wordpress itself is kept up to date.
