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.

Troj/Agent-AAJO is an e-mail-distributed Trojan that targets PC users within the borders of Germany by posing as a PDF notification from a real shipping company. The real company whose brand name is being exploited to install Troj/Agent-AAJO has issued a warning regarding this e-mail, and SpywareRemove.com malware experts recommend that you delete suspicious messages resembling Troj/Agent-AAJO's templates as soon as you see them. Opening the corresponding file attachment, as requested, will infect your PC with Troj/Agent-AAJO without any symptoms of the attack on display. However, if you have become a victim of Troj/Agent-AAJO's ruse, you can relax in knowing that suitable anti-malware tools are more than capable of deleting Troj/Agent-AAJO from your PC.

Troj/Agent-AAJO: a Package with an Unhappy Surprise

E-mail messages spammed out for the purpose of distributing Troj/Agent-AAJO Trojans all use the common scam of posing as package delivery notifications, specifically for 'First Class Zollservice.' Although First Class Zollservice is a real shipping company, they're not affiliated with Troj/Agent-AAJO and have specifically warned German PC users to avoid opening e-mail file attachments that appear to be sent from them. These e-mail messages include minor typographical errors in the German text that may be indicative of the messages being formatted by either an automatic translation tool or an inexpert speaker of the language.

While the above scam is an extremely common method of distributing Trojans like Troj/Agent-AAJO, Troj/Agent-AAJO sets itself a head above the rest of its kind by nature of the raw quantity of its attacks. Spam e-mail messages carrying Troj/Agent-AAJO Trojans have been seen at such high volumes that First Class Zollservice has been forced to put their usual customer service e-mail on hiatus – although the company has provided a second e-mail address that customers of the company and victims of Troj/Agent-AAJO attacks alike may use for the duration of this emergency.

A Few More Reasons Why Seeing Shouldn't Be Believing

Troj/Agent-AAJO's e-mail messages include forges sender fields that make the innocent First Class Zollservice appear to be the original sender, but the actual senders most likely are botnet-operated spambots that may very well be installed by Troj/Agent-AAJO, itself. The file attachment that victims are requested to open also is disguised as a PDF file, but actually is a ZIP archive. SpywareRemove.com malware experts recommend that you display file types by default to avoid being tricked into opening files in this way, and also warn that even real PDFs have been known to host vulnerabilities that could be used to install different PC threats.

If you're sufficiently paranoid to delete Troj/Agent-AAJO's e-mail messages without opening their file attachments, your computer is as good as safe from Troj/Agent-AAJO's current delivery methods. If, on the other hand, you've opened the above file, you should use anti-malware programs to delete Troj/Agent-AAJO before any long-term damage can be done to your PC or information that's stored on it.
