Threat Metric
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.

Trojan.Shylock.B is a Trojan that opens a back door on the affected computer and aims at stealing personal information. Trojan.Shylock.B spreads by exploiting the Oracle Java SE Rhino Script Engine Remote Code Execution Vulnerability (CVE-2011-3544) and Oracle Java SE Remote Java Runtime Environment Code Execution Vulnerability (CVE-2012-0507). Once executed, Trojan.Shylock.B creates the certain file. Trojan.Shylock.B then opens a back door and connects to the command-and-control (C&C) server in order to drop more malicious files. Trojan.Shylock.B collects information about the infected PC and transmits it to the C&C server. Trojan.Shylock.B also injects itself into a 'svchost.exe' process in order to gain commands from the C&C server.
