We don't handle removal requests here, but since your company appears
to be a transportation consulting company, most likely you are
inquiring about a web site that has been cracked (broken into) and
malicious content placed on it. Insecure computers may also be used
for malicious activity such as phishing, DDOS, identity theft, banking
credential theft, etc.
It is crucial that the web site and all computers used to connect to
it have a full security audit done by a competent security expert.
