Cloud Protection is malicious application that will interrupt your surfing the Internet with continuous system scanners and alerts that will be reporting the same thing: Attention! You are infected!. However, this program is not capable to detect or remove anything, so you should simply ignore its alerts and get a licensed anti-malware program which will help you with removal of this scam. One of the most common ways how you can get Cloud Protection installed on your machine is through insecure downloads or updates.
