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
Infected PCs:	101

Trojan:DOS/Alureon.J is a component of Alureon, a Trojan and rootkit that compromises your PC to steal classified information, such as account passwords and bank credentials. Because Trojan:DOS/Alureon.J may compromise your PC's master boot record, making its removal extremely difficult, malware researchers recommend using strong anti-malware utilities, along with all necessary assistance from PC repair professionals to delete Trojan:DOS/Alureon.J and related Alureon components. Failing to remove Trojan:DOS/Alureon.J properly will cause Trojan:DOS/Alureon.J to be re-detected, even after after Windows has been repaired.

The Windows Repair that Doesn't Do Any Good

Trojan:DOS/Alureon.J is a recent version of an MBR-attacking component of Alureon that has been confirmed to be compatible with Windows 8. Because Trojan:DOS/Alureon.J modifies the master boot record to allow other attacks to occur, Trojan:DOS/Alureon.J usually will trigger a 'preparing automatic repair' screen when Windows boots. Casual attempts to remove Trojan:DOS/Alureon.J may result in its being re-detected the next time Windows starts due to the robust exploitation of rootkit-based attacks against the infected PC. However, there are no other symptoms related to Trojan:DOS/Alureon.J's attacks, which primarily are meant to modify your DNS settings to enable botnet 'flooding' attacks and other harmful actions.

Because Trojan:DOS/Alureon.J is a part of the Alureon family, Trojan:DOS/Alureon.J doesn't operate alone. Any single Trojan:DOS/Alureon.J infection also will be found alongside other Alureon-related PC threats, and, potentially, other types of threats. The usual risks malware experts associate with this family include the loss of account-based information that could allow finances to become compromised. Alureon and Trojan:DOS/Alureon.J both are compatible with multiple versions of Windows, including 64-bit and 32-bit, with different infectious behavior for each platform.

Removing Trojan:DOS/Alureon.J Just Once and Making it Stick

Although the use of anti-malware software always is suggested for removing Trojan:DOS/Alureon.J and related high-level PC threats, malware experts also warn that the nature of Trojan:DOS/Alureon.J's installation tends to require some additional procedures. A successful Trojan:DOS/Alureon.J infection requires you to use a backup to restore the corrupted MBR. The details of this step may vary with your version of Windows, but usually will call for using your original installed CD or DVD. If the MBR isn't restored from a corrupted state, your anti-malware programs will continue to detect Trojan:DOS/Alureon.J after Windows starts.

Also referred to as TDSS, Alureon is a family that has been active and, by the standards of threats, highly successful in the past few years. As long as Alureon is in distribution, Trojan:DOS/Alureon.J will continue to be a threat to the MBRs of Windows machines. In some cases, some symptoms like Windows warning messages, anti-malware pop-ups or even a disabled keyboard can be seen. However, Trojan:DOS/Alureon.J and other Alureon Trojans also are able to attack your PC without showing you any visible symptoms during the infection.
