Malware Removal and Website Stabilization

My websites hosted on Ionos are infected with malware/virus. One site is redirecting to the other, while the second goes down often without any specific pattern. This is becoming increasingly problematic. I need an experienced professional to clean up the infection, stabilise both sites and ensure they function independently.

Ideal skills and experience:
- Proven experience in malware removal
- Familiarity with Ionos hosting
- Web development and troubleshooting skills
- Ability to ensure long-term website stability and security
