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:	6/10
Infected PCs:	92

BKDR_ANDROM.NTW is a backdoor Trojan-based component of Andromeda, a multiple-component PC threat that steals confidential information, installs other types of malware, distributes itself as a worm and compromises the security of the infected computer. Andromeda attacks that install BKDR_ANDROM.NTW have been observed to use Trojan downloaders that are disguised as Java updates – a disguise that may catch many an unwary PC user – since Java was recently updated to correct a well-publicized vulnerability. Because of its sophistication and tendency to target sensitive information such as bank passwords, BKDR_ANDROM.NTW and other Andromeda variants should be removed with appropriately advanced anti-malware programs whenever they're available.

How a Variety of Problems Can Spring Forth from a Simple Update

Variants of Andromeda have been found to use exploit kits like Blacole to distribute themselves, but BKDR_ANDROM.NTW uses a slightly different tactic: a Trojan downloader, JAVA_DLOADER.NTW, that's promoted as a supposed update for Java. Aside from minor typos in the download link (which is hosted at a confirmed hostile site), there aren't any visible clues as to JAVA_DLOADER.NTW's true nature until after it's been launched and has installed several components of BKDR_ANDROM.NTW.

BKDR_ANDROM.NTW also may install other PC threats, as SpywareRemove.com malware experts would expect from any malware that's known to use a multi-component structure, and will attempt to subvert the infected PC's firewall and other security features. The foremost threat from BKDR_ANDROM.NTW is its ability to smuggle private information, such as passwords for bank accounts and other financial data, although BKDR_ANDROM.NTW also may block security programs, enable criminals to access your computer or exploit your PC's own resources to distribute itself through social media.

Putting Out the Star of BKDR_ANDROM.NTW with Nothing Lost in the Meantime

If you've installed a Java update from a suspicious source, SpywareRemove.com malware experts suggest scanning your PC immediately and with suitably-powerful anti-malware products. Attacks by BKDR_ANDROM.NTW Trojans are unlikely to show many symptoms, although you may notice resource usage discrepancies that are a result of keylogging and other BKDR_ANDROM.NTW-related attacks. Due to the advanced nature of BKDR_ANDROM.NTW's defenses and basic structure, you shouldn't attempt to delete BKDR_ANDROM.NTW with normal program-removal methods if you do have access to suitable anti-malware tools.

As long as you delete BKDR_ANDROM.NTW completely and quickly, any attacks that your PC suffers through are unlikely to show long-term damage. However, SpywareRemove.com malware research team still encourages you to change any potentially-compromised passwords, along with other security information, after your PC has been disinfected of BKDR_ANDROM.NTW. Failure to do this may allow criminals operating BKDR_ANDROM.NTW servers to compromise accounts associated with your PC even after BKDR_ANDROM.NTW has been removed.

Additionally, you may wish to double-check your social networking-related accounts and removable hard drive devices (USB thumb drives, etc) – since both of these platforms are known to be used by malware with worm capabilities like BKDR_ANDROM.NTW.
