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:	2/10
Infected PCs:	157

Virus.Win32.DelfInject is a semi-generic name for a Trojan that injects its code into system processes to accomplish its functions, which usually involve installing other PC threats. This makes detecting or deleting Virus.Win32.DelfInject difficult without specialized anti-malware software, since, as far as your memory processes are concerned, Virus.Win32.DelfInject appears to be a normal part of your operating system. SpywareRemove.com malware experts also recommend that you keep anti-malware software to defeat Virus.Win32.DelfInject due to Virus.Win32.DelfInject's habit of detecting this software and performing its own deletion (presumably to prevent Virus.Win32.DelfInject from being analyzed) in cases of positive detections. Neither Virus.Win32.DelfInject nor its payload have any form of confirmed symptoms for their attacks, beyond the minimal extra memory usage that Virus.Win32.DelfInject requires for its functions.

Virus.Win32.DelfInject: a Fine Houdini Act for Malicious Software

Although some sources classify Virus.Win32.DelfInject as a virus, SpywareRemove.com malware researchers consider Virus.Win32.DelfInject more properly to be defined as a Trojan downloader or rootkit, since Virus.Win32.DelfInject hasn't been found to distribute itself, like a virus, by infecting many types of files indiscriminately. Instead, Virus.Win32.DelfInject's infection process is distinct and limited to compromising 'rundll32.exe,' which Virus.Win32.DelfInject then uses to delete its original EXE file. Thereafter, Virus.Win32.DelfInject launches itself in memory as part of the svchost.exe process and is indiscernible from the rest of your OS, except for any minor changes in resource usage that you may be able to see.

Virus.Win32.DelfInject's main function is to make contact with remote servers for the purpose of downloading other files, potentially including other Trojans, spyware, configuration data or updates for its own behavior. SpywareRemove.com malware research team, therefore, recommends extremely thorough scans of any hard drive that's infected by Virus.Win32.DelfInject, since Virus.Win32.DelfInject can install other PC threats at its own whim. Common payloads for Virus.Win32.DelfInject and similar Trojan downloaders often include banking Trojans that steal bank account data or PC threats that attack your computer's security software.

Why Virus.Win32.DelfInject's Paranoia Can Be to Your Benefit

At this time, Virus.Win32.DelfInject's confirmed aliases include Trojan.DownLoader5.12990, Win32/Delf.ODS Trojan, VirTool:Win32/DelfInject, Trojan.DR.Injector!8ocyJC5SGmA and Trojan-Dropper.Win32.Injector.uzb. Although Virus.Win32.DelfInject is several years old, its attacks remain functional for most versions of Windows, and SpywareRemove.com malware experts recommend that you take all due precautionary measures against potential Virus.Win32.DelfInject infection routes and attacks.

One interesting trait of Virus.Win32.DelfInject is that Virus.Win32.DelfInject attempts to detect prominent brands of anti-malware software on your PC. While this function isn't unusual ( SpywareRemove.com malware analysts have also seen it, for example, in rogue anti-malware scanners from the FakeVimes family), Virus.Win32.DelfInject's response to a positive detection is a little abnormal - Virus.Win32.DelfInject will terminate itself automatically to avoid detection or deletion. While this neuters Virus.Win32.DelfInject's ability for harm in the short term, you should still remove Virus.Win32.DelfInject later with anti-malware scans as is convenient.
