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.

Threat Level:	9/10

The backdoor Trojan Trojan.Small.hnz earns its categorization as a high-level security risk due to being able to ravage the applications and settings used to defend your computer from attack. Trojan.Small.hnz may also install other malware threats on your computer that can have varied malicious effects. The act of deleting Trojan.Small.hnz is best done with assistance from an expert or a devoted anti-malware product due to the Trojan's corruption of the Windows registry, which makes Trojan.Small.hnz challenging to remove.

Shutting Your Door in the Backdoor Trojan's Face

Through registry modifications, Trojan.Small.hnz will run during the startup of Windows unless exceptionally secure boot options are used. This allows Trojan.Small.hnz to be active constantly without tipping the user off to Trojan.Small.hnz's activity, so it's easier to avoid catching this Trojan than it is to remove Trojan.Small.hnz once you've caught it.

Your anti-malware programs should be kept updated to maximize the likelihood of seeing Trojan.Small.hnz when it first tries to creep onto your PC; Trojan.Small.hnz is relatively new and may be effectively invisible to good anti-virus programs working with outdated threat information. Trojans like Trojan.Small.hnz can be spread through infected .exe files if you're not too careful about what you open, and can even be dropped straight onto your computer through your browser if your settings are too low.

What You Risk by Pitting Your PC Against Trojan.Small.hnz

As far as Trojans go, Trojan.Small.hnz represents one of the highest possible risks to system security because of Trojan.Small.hnz's backdoor-based abilities. Trojan.Small.hnz disables security with the intent of letting a remote attacker get into your machine and control it, damage it or spy on it. Any computer accessible by a remote attacker might as well belong to the criminal instead of you, so take a hard stance against tolerating Trojan.Small.hnz if you think it's squatting on your hard drive premises.

Trojan.Small.hnz is also capable of downloading malware onto your machine. Possible malware can take many forms, such as these:

Keyloggers that make a log of every keystroke you type, or other kinds of spyware that use more intricate means of spying on you and your machine.
Rogue products that copy the appearance of anti-malware programs to hoodwink the user while displaying countless errors and alerts that have no substantial evidence behind them.
Browser hijackers that force your browser to go to malicious websites that can initiate other malware downloads or steal private information.

This barely scratches the surface of the troubles any Trojan can cause; if you suspect an infection, removing Trojan.Small.hnz is the best thing you can do for your computer in the short term or the long term.
