Hello,
I can help you in this... I can scan your server well and will give you the complete report of the malicious or infected files in your server.. I would like to mention one more thing.., if you are referring to your router.., I can't help in that.. but I can help in the server part.. Can you let us know which type of server are you running?
If you contact me, we can discuss this in detail... Looking forward to hear from you...
