NavaShield

NavaShield is rogue antivirus software released for Microsoft Windows. Its purpose is to trick users into downloading with both nagware and malware.

Why it was Crummy

 * 1) It claims to protect computers from viruses, but in reality, it shows that this software was dangerous due to some payloads as listed below.
 * 2) *In short, it did more harm than good!
 * 3) If you played around with date and time, you know your computer is infested with laughing and pornographic sites.
 * 4) Annoying popups, even when the trial has expired.
 * 5) Even worse, if NavaShield went too far, it deleted important files via C drive, thus rendering your computer useless.
