Malware Defense is a badware release with amazing similarities to PC Live Guard and Live PC Care. I’m just guessing, but it seems these guys are just releasing the same fake antispyware over and over under different names! But why would anyone do such a crazy thing? Maybe because these scammers are just trying to make a quick buck before people catch wind of their little racket. Too late. We know this program is a trojan, that its Malware Defense pop-ups are spam, and that its system scans are not real. So, we’re not going to give them any money. Come up with something new, guys. Ready to send these crooks on their merry way? Here’s how to remove Malware Defense for free.
