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

Trojan:Win32/Alureon.FL is the most recent Trojan variant produced by the seditious Alureon family of malware-laced products.
SpywareRemove.com security analysts have categorized Trojan:Win32/Alureon.FL as a high-risk, harmful Trojan that needs to be immediately removed from computers. Upon detection, Trojan:Win32/Alureon.FL needs to be removed from any infected system because allowing this threat to remain on a compromised system for any lengthy period of time is considered significantly unwise.

Trojan:Win32/Alureon.FL is a Dangerous, Privacy-Invasive, Malware-Promoting Security Threat

Reports provided on Trojan:Win32/Alureon.FL have revealed that this Trojan is controlled by a remote host and is very capable of connecting a remote server. Threats, like Trojan:Win32/Alureon.FL, primarily work to connect with remote servers because they function as privacy-invasive threats that log and steal all kinds of confidential-types of data from infected systems for their malicious creators.

In this way,Trojan:Win32/Alureon.FL is a privacy-invading security breach that is known to attempt to violate users' privacy; one primary method, where Trojan:Win32/Alureon.FL can be seen taking part in this particular brand of malicious behavior, is in this Trojan's desire to capture sensitive information stored on compromised systems.

In addition, Trojan:Win32/Alureon.FL is also capable of dropping a variety of other equally or more dangerous malware-laced threats onto compromised machines. This means that this particular Trojan may be utilized to further infect already compromised computers and propagate a variety of rogue security programs, malware applications, spyware, adware, other malicious Trojans, etc.

In fact, several reports released on this malicious threat have noted that Trojan:Win32/Alureon.FL has been discovered promoting and distributing various rogue anti-spyware applications onto the computer systems unlucky enough to be breached by this nasty Trojan.

Other Signs of a Trojan:Win32/Alureon.FL Infection

If your system has been successfully invaded by this Trojan, you should be aware that Trojan:Win32/Alureon.FL is more than capable of manifesting itself on your system in a variety of worrying, frustrating signs and symptoms – a few of which are:

Forcefully redirect infected systems' web browsers.
Restrict or block user access to certain programs.
Fabricate and display bogus pop-up security alerts and messages.
Generate a variety of annoying commercial advertisements on infected systems' desktops.
Dramatically affect the overall performance of compromised computers.
Significantly slow down the processing ability and speed on compromised systems.

Additionally, continuing in the tradition of Trojan:Win32/Alureon.FL's two predecessor family members Trojan:Win32/Alureon.A and Trojan:Win32/Alureon.E, the malicious Trojan also utilizes dangerous rootkit techniques to invade and compromise targeted computer systems. Trojan:Win32/Alureon.FL employs rootkit-type techniques to allow Trojan:Win32/Alureon.FL to gain access to vulnerable machines, and then compromise and damage them without being detected by the systems' existing computer security solutions. These techniques help Trojan:Win32/Alureon.FL evade unwanted detection and removal.

Upon successfully infecting a targeted computer, Trojan:Win32/Alureon.FL immediately works to disable the removal tool completely, which is installed on most Windows-based computer systems that would allow infected users to move this malicious program.
Both of these two aforementioned automatic activities pursued by Trojan:Win32/Alureon.FL are mechanisms meant to allow this vicious program to infect and damage the compromised machines with ease and little need for worry. They basically enable Trojan:Win32/Alureon.FL to more efficiently enact and execute all of its malicious, corrupt processes and activities.
