First of all, what is Ransomware?
Quite simply, Ransomware is malicious software that denies you access to your computer or files until you pay a ransom. Here are a couple of common types: One style which is most common encrypts files such as all the files in your 'My Documents' folder. These files are encrypted and rendered inaccessible. A document is left behind for the victim that includes details on how to pay to get the key to unlock the encryption. Another style will 'lock' the screen and demand payment. In this instance your computer is locked from your use with the a full screen image that provides details on how to pay to unlock the screen.

Ransomware is also a large threat to the home user. Here are some tips to lower the risk in your household:
- Turn on automatic updates for Microsoft, flash and Java
- Install Anti-Virus software and keep it updated
- Avoiding clicking links or opening attachments in emails that you weren't expecting
- Avoid going to suspicious websites or clicking links provided through social media
