When WordPress malware keeps coming back, another surface cleanup is unlikely to solve the problem. Recurrence may indicate remaining persistence, an unresolved vulnerability, compromised credentials or an infected restore. Begin by comparing what changed after each cleanup rather than repeatedly deleting the same visible file.
Build a timeline of the recurrence
Record the first symptoms, cleanup steps and the time the problem returns. Compare file modification times, deployments, account activity and scheduled tasks. A precise timeline can narrow the investigation. Keep compromised snapshots separate from known-good backups and avoid overwriting the evidence before it has been reviewed.
Check persistence and vulnerable components
Review plugins, themes, must-use plugins, uploads, database content and scheduled jobs as appropriate. Unsupported or untrusted components need careful assessment. Compare known software with trusted originals and investigate custom code separately. A clean scan does not rule out a hidden change or an account that can recreate the infection.
Review every relevant access path
Consider hosting, SSH, FTP, WordPress accounts and third-party integrations, using only authorized access. Remove unnecessary privileges and investigate unfamiliar accounts. Rotate affected credentials after the environment is secured. If the cause may involve hosting-level or another linked environment, involve the provider rather than assuming WordPress is the entire scope.
Validate a controlled recovery
Fix the entry route, replace compromised components and restore only verified content. Confirm critical pages and forms work, then monitor for returning changes. Define update, access and backup ownership so the same weak point is not left unattended. Keep uncertainty visible: repeat incidents need evidence-led investigation, not a promise that one plugin will solve everything.
Questions to consider
Should I install more security plugins?
Additional tools can help monitoring, but they do not replace fixing the entry route and removing persistence. Multiple overlapping tools can also complicate diagnosis.
Can an infected backup cause reinfection?
Yes, restoring compromised material can reintroduce the problem. Validate the backup and address the original cause before relying on it.
