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.

Evaman.a is a mass mailing worm that propagates through email. Once installed and executed, Evaman will embed itself into your Windows registry so that it can automatically start when Windows starts. Then Evaman.a will try to connect to a list of SMTP servers (or your PCs default SMTP server). Evaman.a will build up a list of email addresses to target by using the email address search feature of Yahoo mail. This involves making HTTP requests to: email.people.yahoo.com and will gather email addresses from the results. It will then send its copies to any emails that it is able to collect, as either an exe file or an scr file. Emails sent out by W32/Evaman-A pretend to be automatic responses from a mail server, and may have one of the following subject lines: "returned mail", "failure delivery "," mail failure "," failed transaction,"etc.
