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.

Worm.Rorpian.E is a malicious computer worm that proliferates via network shares and by exploiting the Domain Name System (DNS) Server Service vulnerability. Worm.Rorpian.E also downloads and installs additional malware infections on the infected computer system. Worm.Rorpian.E makes some system changes, that is, contacts a particular IP address to download some files and modifies the registry. Worm.Rorpian.E replicates by enumerating all network shares; copying itself to the share, together with numerous other files. Worm.Rorpian.E also creates an 'autorun.inf' file that initiates Worm.Rorpian.E executable when the share is accessed, and a shortcut .lnk file which exploits the certain vulnerability. Worm.Rorpian.E does a network scan in order to find exploitable computers, copying itself to the computer if it is vulnerable. Delete Worm.Rorpian.E as early as possible from the affected machine.
