Malware creation and deployment are a global, multi-billion dollar industry. Your computer can either be compromised by criminals to obtain your own financial information, or your computer can be used to aid criminals in illegally gathering information or resources to make themselves money. Either way, it has major negative and economic impacts for both individuals, and businesses. Here is a current look at the most destructive malware in terms of data loss and financial losses.
Cryptolocker – Ransomware
What it does: Cryplocker completely locks computers and encrypts data. Currently, the ransomware demands $300 to receive a code to retrieve encrypted files.

How do you get it? Cryptolocker is most commonly spread through email attachments.

How do you get it? Users have to download the software. Alureon is commonly bundled and hidden in rogue security software.
