Do you know what Files Secure is?
Files Secure is a rogue anti-spyware program that may display fake warning messages and run a false malware detection in order to make you believe you're machine is infected with spyware.
Files Secure displays exaggerated security alerts in an attempt to trick you into purchasing the full Files Secure version. Files Secure error message states that your computer is infected or hijacked with a type of Trojan and that you need to download Files Secure to solve your problem.

Once Files Secure finishes scanning you computer, it will report false positives and message will appear that prompts you to click the button to download the recommended software to remove the alleged infection. That way you're persuaded to buy the Files Secure program.
In non-techie terms: Distributors of trojans conduct illicit installation methods to extort money from you. Do not download free video codecs from questionable websites. You're only asking for trouble and the Trojan infection, as well as Files Secure, can be difficult to remove.
