This problem is known as "Cross site scripting" or "SQL Injection" attack.  These attacks are done by web users who can scan your website using some internet robots and can get hold of the coding and other relevant details about the server like web server version, scripts language and database type.Malicious codes as well as some scripts and Iframes that redirect to other sites containing virus gets embedded automatically for which they don't need any access to the server. These types of infection is called "Cross-site scripting" which operates on the vulnerability in the website and exploits them (like non filtered input in the search/ contact/ login/ any type of submit page).
