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:	319

Mal/20113544-A is a JavaScript-based exploit that installs other PC threats, eventually resulting in infection by a backdoor Trojan (with the exact type of Trojan involved varying, depending on the victim's operating system). Since Mal/20113544-A, like other drive-by-download attacks, can initiate its download without your consent and may be embedded into several websites, SpywareRemove.com malware researchers recommend that you use an updated web browser alongside strong security software to prevent Mal/20113544-A from attacking your PC. Users of Mac OS X earlier than 10.6 are particularly noted as being vulnerable to Mal/20113544-A attacks, since there is no security update to protect against Mal/20113544-A's exploit (unlike more recent versions of Mac and most versions of other operating systems, including Windows and Linux). Although there are no symptoms coinciding with a Mal/20113544-A attack, Mal/20113544-A can be used to install various PC threats and should always be considered a serious security risk.

Why Lag in Updating Could Mean a Chance for Mal/20113544-A to Strike

Most operating systems have been protected against Mal/20113544-A since February of 2012, provided that all prospective victims habitually install all available security patches. SpywareRemove.com malware researchers have found that Mac-based users, however, are somewhat more at risk than most victims, since their corresponding anti-Mal/20113544-A update was only seen in April, and as noted above, isn't all-inclusive for all versions of that platform. As a Java-based attack, Mal/20113544-A can be deflected by keeping JavaScript disabled by default or even uninstalled. Most popular browsers will allow you to disable scripts like Java selectively and on a site-by-site basis.

Current Mal/20113544-A (also known as Exploit.Java.CVE-2011-3544.ad) attacks automatically launch a related Trojan attack, Mal/JavaCmC-A (also known as Trojan-Downloader.Java.Agent.ac or TR/Skurtle.1706). This second PC threat will finally end up installing a backdoor Trojan – SpywareRemove.com malware analysts have found that Windows-based victims will incur a Mal/Cleaman-B Trojan, while Mac victims will suffer through an OSX/FlsplyDp-A Trojan infection, both of which will install other PC threats. Either instance should be considered a high-level threat to your computer's security that allows criminals to access and control your PC – including allowing access to personal information or enabling security-related attacks.

How to Enjoy the Web without Mal/20113544-A in the Way

As a website-based attack, Mal/20113544-A can be avoided by avoiding websites that have been compromised recently or are known to host suspicious content. Any successful Mal/20113544-A attack will result in additional PC threats being installed directly onto your PC without your permission, and for this reason, SpywareRemove.com malware analysts stimulate you to scan your computer with security software after any contact with a potentially Mal/20113544-A-contaminated website. Installing all relevant security updates for your browser, operating system and JavaScript package can also help to close security exploits like the one that Mal/20113544-A uses in its attacks.

Files that are related to a Mal/20113544-A attack have been known to misrepresent themselves in their file names – for example, by naming themselves after legitimate software installation packages. Because backdoor Trojans like those that are installed by Mal/20113544-A are also often guilty of stealing personal information to enable account-related hijacks and other crimes, SpywareRemove.com malware experts also encourage you to use good safety procedures after cleaning up the aftermath of a Mal/20113544-A attack. Changing passwords, contacting relevant companies and taking other methods to ensure that any stolen information isn't misused can be the difference between a safe bank account or an empty one.
