TrojanDropper:MSIL/VB.I

Posted: February 22, 2011

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:	8/10
Infected PCs:	379

Just as the name implies, TrojanDropper:MSIL/VB.I is a Trojan that drops malware onto your computer. TrojanDropper:MSIL/VB.I may be distributed in software bundles, especially through P2P and other large-scale file-sharing networks. Infection by TrojanDropper:MSIL/VB.I has been classified a severe threat, because this Trojan will install malware without your consent and may also serve as a backdoor for remote hacker assailants. Deleting TrojanDropper:MSIL/VB.I should usually be handled by reliable software programmed for the task, since some reports have indicated this Trojan to be polymorphic and correspondingly hard to identify.

TrojanDropper:MSIL/VB.I is Every Other Trojan's Best Friend

TrojanDropper:MSIL/VB.I has several functions, but its primary risk comes from its ability to download and install malware in secret. Any system infected with TrojanDropper:MSIL/VB.I will rapidly find itself infected by other attackers as well, and these other malware invaders may or may not give any readily observable inklings of their presence. Some other popular types of malware can allow remote attackers to spy on or control your computer, hijack your browser or create fake system alerts. If you don't delete TrojanDropper:MSIL/VB.I when you first see Trojan.Win32.Scar.dimu, the next day may very well be too late!

As a secondary danger, TrojanDropper:MSIL/VB.I can also reduce your security deliberately to enable remote attacker access. This is tantamount to giving your computer away to a hacker with all information and system resources still intact. Even without obvious signs of a remote attack, the attacker may still be using keylogging malware or other spyware to record and steal all information that passes through your machine.

How Your Computer Contracted the TrojanDropper:MSIL/VB.I Taint

TrojanDropper:MSIL/VB.I has been reported to be distributed as part of bundled packages with other software. Its presence is particularly likely on large-scale file-sharing services such as P2P networks, where security against Trojans like TrojanDropper:MSIL/VB.I is low.

The TrojanDropper:MSIL/VB.I infection may also be difficult to spot because some reports have given an indication of polymorphic (or shape-changing) abilities. This trait allows malware to change its appearance while keeping all core functions intact, making problems like TrojanDropper:MSIL/VB.I quite difficult to stomp out. In particular, file and process names may change completely after a reboot, so you shouldn't try to identify TrojanDropper:MSIL/VB.I without help in most cases.

Relying on popular and updated security tools is your most likely salvation against TrojanDropper:MSIL/VB.I. Any anti-virus program that hasn't been updated since November of 2010 may not be capable of deleting TrojanDropper:MSIL/VB.I, so check the date on that malware definitions file every once in a while!
