Good Read! @Neemobeer Bottom line! Quote taken from the link provided! For those not familiar with ransomware. It's a bad dude!
Microsoft Malware Protection Center - Ransomware
"We strongly encourage users and organizations
to follow recommended security practices, such as installing security patches as
they become available, exercising caution when receiving messages from unknown
third-parties, and ensuring a robust backup solution is in place. These practices will
help reduce the threat of a compromise and should aid in the recovery of any
such attack."

CryptoWall 4 is really a stobborn ransomware. The ransomware usually gets distributed via some common channels like compromised E-mail, drive-by download and unsecure web link. The data reveal that in most cases victims received infected E-mail before their data locked by the ransomware. When unsuspicious users download and open the attachment of the spam E-mail, they will not realize the truth that they are introducing dangerous programs to their computers. Have you successfully removed the ransomware? If haven't, this article is mainly created to introduce the detailed removal steps to remove CryptoWall. You can have a look.

Here, I would like to introduce some secuity tips to help you prevent ransomware infection and protect your Privacy
Block the activity of executable files and zip files from your Email inbox and pay special attention to the Email from strangers.

Never click on unknown links, emails, pop-up messages, and Email attachments in particular.

Frequently back up all your important data and the system. But please note that if your backups are stored on an external hard drive that is connected to your computer, those data would be encrypted by CryptoWall 4.0 too.

Use strong passwords and do not use the same passwords for all accounts on different websites especially your online banking account. Password services or Password manage tools are not recommended as there is the possibility that they could be hacked.

Limit access to your hard drives by stopping unidentified users from changing files.

Keep your computer system and your websites’ systems, browsers, and plugins up to date. All users should frequently check if there is update available for use, if there is, download it immediately. Or you can activate automatic updates features which can patch security flaws timely.
