My review site was hacked several times and once again I identified malware. It is possible that some of the applications are vulnerable to attacks (to SQL injection attacks or XSS attacks).

Need a person who can analyse PHP code for safety and can create a stable version. Please check my site (swiss recommend . ch) and provide me your suggestions for improvement.

The malware is coming from this file:
