Website malware removal is a recovery process, not simply deleting the first suspicious file. A compromised site may contain altered files, database entries, stolen access or scheduled tasks that restore the infection. Work within authorized access and preserve the information needed to understand what happened.
Record the symptoms and protect evidence
Document redirects, warnings, unfamiliar accounts and recent changes. Coordinate with the hosting provider where needed and consider limiting public access if visitors are being exposed to harmful content. Preserve a copy of affected files and relevant logs before cleanup, stored away from publicly accessible directories. Keep known-good backups separate from the compromised snapshot.
Investigate the whole affected scope
Review core files, extensions, themes, uploads, database content and scheduled tasks as appropriate to the platform. A scanner can identify known patterns but may miss custom or hidden changes. Compare against trusted original software where possible. Do not assume the file showing the symptom is the point of entry.
Clean and close the access route
Replace compromised software from trusted sources and remove unauthorized changes carefully. Fix vulnerable or unsupported components and review user privileges. Rotate affected credentials after the environment is secured so new secrets are not immediately exposed again. Recovery from a backup needs validation of both its date and the vulnerability that allowed the incident.
Validate recovery and monitor
Check public pages, forms and administrative behavior. Review whether unexpected files or redirects return. If a search or browser warning was issued, follow the appropriate review process after the underlying problem is resolved. Keep a recovery record and define monitoring, update and backup responsibilities to reduce repeat incidents.
Questions to consider
Is a clean scan proof of complete recovery?
It is useful evidence, but not a complete guarantee. Combine scans with integrity checks, access review and monitoring.
Should I restore the latest backup?
First assess whether it predates the compromise and whether the original entry point has been addressed.
