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:JS/BlacoleRef.CW is a JavaScript Trojan that propagates via hacked websites. Trojan:JS/BlacoleRef.CW is produced to load a hidden IFrame that loads behind the victim's web browser, rerouting it to an exploit server known as 'Blackhole'. When Internet users activate any links within IFrames while viewing web content on infected websites, their computers become affected by Trojan:JS/BlacoleRef.CW. A hacked website may enable a cybercrook to successfully add a client-side script, which then launches when a computer user visits the hijacked website. Trojan:JS/BlacoleRef.CW's payload may be different, based on what the reference host brings at the time of hijack. The combination of obfuscated JavaScript within a hidden IFrame referencing a malevolent host, and the infectious host itself, which is responsible for dynamically generated content intended at exploiting numerous vulnerabilities on the targeted PC, are monitored and could be changed by a cybercrook at any time enabling it to be highly adaptable to the hacker's requirements.
