Ransomware has made yet another return online as a new and improved version, now dubbed CryptoWall 3.0.

The CryptoWall is an advanced ransomware virus that encrypts your files, making them inaccessible and non-recoverable aside from the criminal’s own doing — which they demand high payment to do.

Normally, these malicious programs are distributed through attachments that users are prompted to download either through .zip files in emails, or links on websites. However, it is now reported that criminals are not using major online advertising to lure unaware users into downloading it — clicking on the displayed ads (even on popular, high name websites) would take the user to an infected website that would in turn download the CryptoWall onto their computer.

As such, please be careful with your internet browsing, and do not click or visit any suspicious ads or websites!
