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:	10/10
Infected PCs:	12

TrojanDownloader:Win32/Nemim.gen!A is a Trojan that can install various payloads, with currently-analyzed TrojanDownloader:Win32/Nemim.gen!A attacks including the installation of e-mail account-hijacking spyware programs and viruses that use removable drives to distribute themselves. Like some of the other sophisticated PC threats SpywareRemove.com malware experts have looked over, TrojanDownloader:Win32/Nemim.gen!A also includes some functions to prevent the anti-malware industry from analyzing TrojanDownloader:Win32/Nemim.gen!A – most particularly, the ability to delete the other Trojans that TrojanDownloader:Win32/Nemim.gen!A installs. TrojanDownloader:Win32/Nemim.gen!A should be considered an aggressive threat to your computer, and suitable anti-malware programs should be used to delete TrojanDownloader:Win32/Nemim.gen!A and any other Trojans that could be installed by TrojanDownloader:Win32/Nemim.gen!A.

Why Relying on TrojanDownloader:Win32/Nemim.gen!A to Delete Your Problems Could Backfire

TrojanDownloader:Win32/Nemim.gen!A plays the well-defined part of a Trojan downloader, a Trojan that is used to download and install other forms of specialized malware, but also includes some features that are relatively unique to TrojanDownloader:Win32/Nemim.gen!A. With the race between the anti-malware industry and the malware criminal 'industry' as a constant neck-and-neck ordeal, TrojanDownloader:Win32/Nemim.gen!A exemplifies just how far malware authors will go to avoid being detected: by deleting their own Trojans. If TrojanDownloader:Win32/Nemim.gen!A detects that TrojanDownloader:Win32/Nemim.gen!A is on a PC related to anti-malware analysis, TrojanDownloader:Win32/Nemim.gen!A will proceed to delete any payloads related to TrojanDownloader:Win32/Nemim.gen!A, making them impossible to analyze.

Since TrojanDownloader:Win32/Nemim.gen!A has access to a hefty range of different servers from which TrojanDownloader:Win32/Nemim.gen!A can download its payloads, the other PC threats that are related to TrojanDownloader:Win32/Nemim.gen!A have a high potential for flexibility. However, SpywareRemove.com malware researchers consider the following PC threats to be some of the most probable TrojanDownloader:Win32/Nemim.gen!A-related infections:

PWS:Win32/Nemim.A is spyware. It steals various basic OS information (that could be used in future attacks against your PC), instant messenger login credentials and e-mail account login credentials. The theft of the latter information is achieved by PWS:Win32/Nemim.A analyzing cached login data, which is just another reason why SpywareRemove.com malware experts rate the unnecessary saving of login information as a potential security hazard.
Virus:Win32/Nemim.gen!A is a virus, but only infects specific files: EXE files that are located in removable drives (like any USB device) and the OS's Hosts file. The former target of infection can be used to infect other PCs that launch the Virus:Win32/Nemim.gen!A-infected executable file from the compromised device.

Taking Your Trojan Deletion Into Your Own Hands

Although TrojanDownloader:Win32/Nemim.gen!A does have the ability to delete other PC threats that TrojanDownloader:Win32/Nemim.gen!A installs, this function never should be assumed to protect your PC from TrojanDownloader:Win32/Nemim.gen!A's attacks – since its only purpose is to delay anti-malware analysis. Updating your anti-malware applications also is important for allowing them to detect TrojanDownloader:Win32/Nemim.gen!A, Virus:Win32/Nemim.gen!A and PWS:Win32/Nemim.A, which were identified very recently.

TrojanDownloader:Win32/Nemim.gen!A is a high-level threat to your PC, and SpywareRemove.com malware experts never encourage trying to delete TrojanDownloader:Win32/Nemim.gen!A manually. Once you've disinfected your PC of TrojanDownloader:Win32/Nemim.gen!A, you also may need to change any passwords or other compromised information that TrojanDownloader:Win32/Nemim.gen!A-abusing criminals could use to take control of your accounts (as noted earlier in this article).
