"Website Security, Audit and Protection Services" if we are speaking about a company that scans websites, detects viruses, cleanupremoves viruses from websites from viruses and then setupsets up virus protection.
See my amendments to your post. Your description of the company is rather wordy and long-winded. I would say that it is a company "which scans for, detects and removes viruses, and then sets up virus protection".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
