Wordfence repairs WordPress.org files and sells human cleanups. WP Freedom keeps the evidence, explains each change and rescans to prove what is gone.
A second infection usually means the first cleanup removed what was visible and left whatever let the attacker back in. A backdoor in the uploads folder, a scheduled task that writes the file again, an administrator account nobody remembers creating. Deleting files by hand makes it worse, because those files are the only record of how the site was entered. WP Freedom works the problem in order. It preserves each item before it touches it, removes or replaces what is malicious, then rescans and tells you which indicators are gone and which came back.
If you want someone else to do the cleanup, or a firewall in front of the site, Wordfence is the stronger choice and WP Freedom does not replace it. Wordfence also says its paid cleanups cover one site per license and are not available for WordPress Multisite. The two plugins can run on the same site. WP Freedom earns its place when you or your developer are doing the work and need every change explained, every removal reversible and proof that the indicators are gone.
