I would try disabling any new plugins you have installed first.
If that doesn’t fix the problem you may need to reinstall WordPress and manually remove bad code from infected files.
Once you reinstall WordPress, go through each file in your theme and look for a PHP function called base64_encode. Usually this is the first line in each infected file. Delete this lines in every file.
If your site is hosted on a Linux machine and you have SSH access I would recommend using the grep command to look for the base64_encode function in the wp-content folder.
Here is an example:
grep -rl “base64_encode” /path/to/wp-content
