How to Remove “zzzzz” Virus (Ransomware)
What is zzzzz Virus?
zzzzz virus is a term used to identify a specific variant of Locky ransomware that appends the .zzzzz file extension and file type to the files it encrypts and holds for ransom. It is the latest file extension used by Locky after .aesir. Furthermore, there are many other variants of this ransomware that use different file extensions.
Once the ransomware has encrypted files on a computer it will download a ransom note named -INSTRUCTION (or other) in each folder it encrypted files in, change Windows desktop background, and display a page that says “IMPORTANT INFORMATION” to the user. The ransom note explains what happened to the encrypted files and describes the malware author’s method to pay a ransom in order to obtain a private decryption key. The ransomware may also display a lock-screen that restricts access to the infected machine and change the background of Windows desktop to an image of the ransom note.
