Ykcol Ransomware, a newly break-out ransomware, is the latest version of locky spelled backwards. This variant is currently being distributed via spam emails that have a subject line of Status of invoice, which contain a 7zip, or 7z, attachment with *.vbs script. After double clicking the script, it will automatically download an executable virus named "HdOWSy.exe" and then begin to encrypt your computer files and all shared documents in the same LAN. So your encrypted files could be controlled remotely.

Note this:

Hackers usually do not send any decryptors or decryption keys even if you pay them. Wait until working decryptor appears or try to restore .ykcol files manually from backup or using instructions below.

When it starts working, it will modify and append the name of the files with ".Ykcol". After encrypting, you will encounter such alert:

However, since Ykcol Ransomware spreads mainly through spam, you may worry about the possible threats from the leftover infected scripts. In this way, well-known anti-malware software like Malwarebytes, Bitdefender is preferred than Advanced SystemCare Ultimate.

Last, but not least, make sure you practice the following good online security habits, which in many cases are the most important steps of all:

1. Back up your good-shape system.

2. Do not open attachments if you do not know who sent them.
