The following fields listed on the Threat Meter containing a specific value, are explained in detail below:
Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.
Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.
Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.
Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.
% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

The Xorist-XWZ Ransomware is meant to encrypt the files of its victims and then offer to provide them with decryption instructions in exchange for a ransom payment. The threat has reused a significant portion of the Xorist Ransomwar's code and, thankfully, this is likely to mean that the Xorist-XWZ Ransomware can be decrypted for free without seeking assistance from its authors.
Despite the potential availability of free decryption software, the Xorist-XWZ Ransomware is not a threat that should be underestimated certainly. Its authors have programmed it to encrypt a broad range of files such as documents, photos, videos, spreadsheets, archives, backups, and various file formats related to popular software suites. Whenever the Xorist-XWZ Ransomware encrypts a file successfully, it also will alter its name by appending the '.xwz' extension (e.g. 'backup.bak' would be renamed to 'backup.bak.xwz').
After completing its attack, the Xorist-XWZ Ransomware will drop a ransom message via the file 'READ ME FOR DECRYPT.txt.' The instructions state that the victim's data is impossible to recover without the use of specialized decryption software, which can only be obtained by messaging Blackstarmafia@qq.com and following the instructions of the attackers. The ransom note contains a unique victim ID and a short guide on how to purchase Bitcoins since this is the preferred payment method of the attackers.
If you believe that your hard drive's contents were encrypted by the Xorist-XWZ Ransomware, then you should disregard the instructions of the perpetrators of the attack. Sending them money is unlikely to resolve the problem so that you should focus on alternative file recovery methods. However, your first task must be the full removal of the Xorist-XWZ Ransomware, which can be completed with the assistance of a trustworthy anti-virus software suite. After you remove the threatening application, you are free to use the free Xorist decryption software or alternative file recovery tools.
