Threat Metric

The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to give every identifiable malware threat. Our Threat Meter includes several criteria based off of specific malware threats to value their severity, reach and volume. The Threat Meter is able to give you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count, Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic breakdown of how all threats are ranked within our own extensive malware database. The scoring for each specific malware threat can be easily compared to other emerging threats to draw a contrast in its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to remove a threat or pursue additional analytical research for all types of computer users.

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.

Win32/TrojanDownloader.Agent.QXN is both a Trojan dropper and a worm that installs additional types of malicious files while Win32/TrojanDownloader.Agent.QXN seeks to spread via removable and/or networked drives. Win32/TrojanDownloader.Agent.QXN uses deception both in its installation method, via a fake package delivery e-mail, and during the course of its attacks (by concealing itself inside of a fake Windows process). Symptoms of Win32/TrojanDownloader.Agent.QXN can vary due to its configurable payload, and SpywareRemove.com malware experts recommend that you trust an accurate anti-malware product to detect and remove Win32/TrojanDownloader.Agent.QXN. Until this is done, you should be wary about sharing drives, folders or other resources with other computers, since Win32/TrojanDownloader.Agent.QXN may use these resources for its own distribution.

Win32/TrojanDownloader.Agent.QXN - Beware This Secret Santa

Although Win32/TrojanDownloader.Agent.QXN may also be distributed by other methods (such as e-mail messages about fake ACH payments), the latest Win32/TrojanDownloader.Agent.QXN attacks have been linked to fake package delivery notifications that are spammed to arbitrary e-mail accounts. These professional-looking e-mail messages, supposedly from the Canada Post, claim that a package delivery failed because no one was there to receive it. The Win32/TrojanDownloader.Agent.QXN e-mail even contains a legitimate Canada Post link above a fake link that contains a .pif-based delivery mechanism for Win32/TrojanDownloader.Agent.QXN. SpywareRemove.com malware research team has noted that this fake link has been masked so that its URL appears to be similar to the legitimate link, even if the actual destination is completely-different. In general, it's recommended that you avoid launching .pif programs that aren't from trustworthy sources, since they can be exploited to open program files.

If you do click this link and run the resulting file (which may be launched automatically, depending on how much or how little your security settings stand between you and this action) Win32/TrojanDownloader.Agent.QXN will infect your PC and proceed to unload its rather non-jolly payload of malicious programs.
