c99/c100c99 and c100s are hidden backdoor shells - one of the most common methods used to attack websites with malware. They're placed into the hosting account and allow hackers to access compromised websites whenever they like. Through them they can infect webpages, send out spam email, install phishing pages and worse. Hackers find their targets by identifying a vulnerability on a website (usually an application vulnerability such as XSS or SQL injection). They're hard to find and tricky to delete - only the hacker knows the exact URL location. HackAvert® is your best weapon against c99 and c100 shells.
