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

Trojan:MSIL/Vbato.A, sometimes considered a variant from the Vundo family, is a dropper Trojan that installs other types of malicious software onto your PC, most prominently spyware and scamware products. Since SpywareRemove.com malware researchers have found that many variants of Trojan:MSIL/Vbato.A are capable of injecting their code into normal system processes, you may not be able to notice individual files or processes of a Trojan:MSIL/Vbato.A infection. The symptoms that a Trojan:MSIL/Vbato.A infection exhibits can also vary and may not be significantly visible, which is why you should use a suitable anti-malware product to find and delete Trojan:MSIL/Vbato.A before serious harm is done.

The Numerous Forms and Faces of Trojan:MSIL/Vbato.A

Trojan:MSIL/Vbato.A was first defined as a PC threat in August of 2010, but Trojan:MSIL/Vbato.A infections are still criculating and are capable of being a danger to any Windows PC. Unlike more well-defined Trojans such as Zlob or Fake Microsoft Security Essentials Alert, Trojan:MSIL/Vbato.A is identified by a multitude of different labels depending on which brand of software detects the infection. The following names are all popular aliases for Trojan:MSIL/Vbato.A:

Trojan-Dropper.Win32.Vundo
Trojan/Win32.CSon
Win32/ASuspect.HHKHD
Trojan.PWS.Panda.171
Win32:Inject-ZP
Trojan-Spy.MSIL.Agent.bza
PSW.Generic8.LHQ

Other minor variations can also be seen, but the majority of AV brands will list Trojan:MSIL/Vbato.A as some subtype of Trojan-Spy.MSIL.Agent.bza. As many of its aliases imply, Trojan:MSIL/Vbato.A is noted for its tendency to install spyware. Spyware may take a variety of forms, but common forms of spyware-based attacks include keylogging (recording keyboard input to a log file), capturing screenshots and stealing passwords and other login-related information.

Keyloggers and other forms of spyware that Trojan:MSIL/Vbato.A may install must access the Internet, to send their stolen information to criminal entities; because of this, a common secondary symptom of spyware infections is unusually altered network settings. As long as Trojan:MSIL/Vbato.A and related infections are on your PC, you should be aware of the possibility of open network ports or program exceptions that are added to your firewall without your consent.

Related Threats That Trojan:MSIL/Vbato.A May Utilize Against Your Computer

SpywareRemove.com malware researchers have found that the majority of dropper Trojans, including Trojan:MSIL/Vbato.A, are configurable and can install many different types of malicious programs. In addition to spyware-related perils, a Trojan:MSIL/Vbato.A infection may also subject you to fake security programs (or rogue security applications) that create false positive alerts, browser hijackers that change the websites that your browser displays, rootkits that infect normal Windows processes or other Trojans, such as VirtuMonde.prx.

If you believe that Trojan:MSIL/Vbato.A is on your computer, you should assume that Trojan:MSIL/Vbato.A is active, until you've used Safe Mode or another secure boot option to verify that Trojan:MSIL/Vbato.A hasn't launched. Deleting Trojan:MSIL/Vbato.A, even with advanced security or anti-virus software, may be impossible, if you don't stop Trojan:MSIL/Vbato.A from launching beforehand. Manually removing Trojan:MSIL/Vbato.A isn't suggested, in most situations, due to the high probability of other infections existing on your computer, as well as the probability of Windows Registry changes.
