Removal instructions for Security Shield (2)

1 post in this topic

What is Security Shield?

The Malwarebytes research team has determined that Security Shield is a fake anti-malware application. These so-called "rogues" use intentional false positives to convince users that their systems have been compromised. Then they try to sell you their software, claiming it will remove these threats. In extreme cases the false threats are actually the very trojans that advertise or even directly install the rogue. You are strongly advised to follow our removal instructions below.

How do I know if I am infected with Security Shield?

This is how the main screen of the rogue application looks:
