What is "navashield"

NavaShield is a fake antivirus software. It fools users into downloading and installing malicious software ("malware") by giving them false alerts and running fake scans with exaggerated results. Using these results, it tries to fool the user into buying a "full" version of the product. However, all NavaShield really does is give false results in virus scans, download more malware and, for those fooled into buying the registered version of the fake product, commit identity theft.
