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:	9/10
Infected PCs:	12

Trojan.Script.Heuristic-js.iacgm is a website-based PC threat that is part of drive-by-download attacks to install threats onto your computer – in many cases, by exploiting software vulnerabilities that let them do so without requiring your consent. The last confirmed Trojan.Script.Heuristic-js.iacgm attack has been especially newsworthy for being inadvertently served by a Web page owned by the FireEye PC security company – although Trojan.Script.Heuristic-js.iacgm's actual attack was hosted on a third-party advertisement rather than on the FireEye website. For now, any recent unprotected contact with FireEye-owned domains should be considered a potential brush with spyware-installing unreliable content, and SpywareRemove.com malware analysts encourage using good anti-malware products to protect your browser from Trojan.Script.Heuristic-js.iacgm or remove its payload after its attack.

When the People that are in Charge of Protecting Your Computer Manage the Opposite

Drive-by-downloads hosted at unsafe or compromised sites are one of the more favored methods of distributing high-level PC threats – since they don't require victims to consent to the installations and may benefit from a natural flow of traffic that results in exposure to the attacks. Trojan.Script.Heuristic-js.iacgm is one of the clearest examples of malware authors seeing a preexisting traffic base – in this case, the visitors of FireEye's careers website – and exploiting it.

Trojan.Script.Heuristic-js.iacgm and other PC threats related to its drive-by-download attack were hosted on a compromised advertisement network that, in turn, was loaded by this website. FireEye has since acted to remove Trojan.Script.Heuristic-js.iacgm and all related PC threats, although previously affected visitors to the site may remain compromised.

Current evidence suggests that this attack was a happy coincidence for the malware authors as part of a general advertisement network-based attack rather than an attempt to compromise FireEye specifically. Trojan.Script.Heuristic-js.iacgm, for its part, merely is a common type of risky script that is involved in redirects that force your browser to load compromised JavaScript. What ultimately is downloaded and installed through this attack still is under analysis, although members of the Reveton family of Police Trojans Trojans, as well as variants of Fareit (such as PSW.Win32.Fareit.acqv) or Trojan Zeus, appear to be the predominant possibilities.

The Shield Between Your Browser and a Problem Like Trojan.Script.Heuristic-js.iacgm

Even though FireEye has since remedied this latest Trojan.Script.Heuristic-js.iacgm outbreak, similar attacks are likely to continue being hosted through other websites with less diligent maintainers than the average PC security company's employee. SpywareRemove.com malware experts consider browser-based security procedures, such as disabling JavaScript and keeping your browser updated, to be important parts of blocking Trojan.Script.Heuristic-js.iacgm, which may attack your PC without any showmanship or symptoms.

The payloads currently associated with Trojan.Script.Heuristic-js.iacgm attacks are high-level PC threats that may display fraudulent police warnings, lock your desktop, block other programs or attempt to intercept confidential information to steal. Using competent anti-malware tools always is encouraged for removing the payloads of drive-by-download attacks, and this continues to be applicable to attacks related to Trojan.Script.Heuristic-js.iacgm.
