Trojan.Necurs.A
Posted: September 30, 2011
Threat Metric
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.

Trojan.Necurs.A is a member of a family of rootkits with backdoor and downloader functions, letting them compromise the security of your PC for remote control and install specialized threats for other attacks. While only limited information about Trojan.Necurs.A currently is available, malware researchers have noticed its presence in recent payloads of Trojan Zeus, a well-distributed and regularly-updated spyware Trojan that focuses on compromising bank accounts. Targeted e-mail attacks and drive-by-downloads from harmful websites are the two distribution methods that seem to be at fault for the new rise in Trojan.Necurs.A infections, and malware experts consider the removal of Trojan.Necurs.A with reliable anti-malware products to be an urgent priority for your PC's safety.
The Trojan that's Happy to Weave a Curse on Your PC's Security
Trojan.Necurs.A is one of the newest versions of Necurs to be distributed with some help from other high-level PC threats. Past Necurs attacks have involved such hazards as the Blackhole Exploit Kit (a drive-by-download attacker) and WinWebSec (a family of fake security programs), whereas Trojan.Necurs.A is primarily associated with a rise in United States-targeted e-mail attacks. These attacks use fake delivery notifications and similar formats to trick victims into opening a harmful file attachment containing the Trojan Upatre. Upatre installs a variant of Zeus, which you'll know about if you've read many of our previous articles, while Zeus also installs Trojan.Necurs.A (since, besides being a potent banking Trojan, Zeus also includes functions for downloading other threats).
Trojan.Necurs.A's full capabilities still are under analysis, although malware experts estimate that Trojan.Necurs.A most likely is intended to be an anti-security measure for protecting other PC threats installed by the same e-mail. Trojan.Necurs.A may block security programs, open a backdoor vulnerability on your PC to let criminals access it, install new types of risky software or upload data stolen by other means to a criminal-controlled server.
Even though Necurs rootkits sometimes are involved with payloads that show major symptoms, like WinWebSec, these latest attacks with Trojan.Necurs.A all use PC threats that try to hide themselves. As a result, symptoms of the infection may be minimal – especially without anti-malware utilities to detect Trojan.Necurs.A.
Dispelling Trojan.Necurs.A Before It Can Expel Your Money
Trojan.Necurs.A and the other threat related to Trojan.Necurs.A are especially well-known for the advanced programming involved in their attacks and anti-security features, and also for targeting personal information such as account passwords for your bank account. Even though you may not see any obvious signs of something wrong with your computer, malware experts always consider a Trojan.Necurs.A infection to be a high-level security and privacy hazard. Deleting Trojan.Necurs.A immediately, and with proper anti-malware tools, is paramount for the future security of any infected computer.
By the raw numbers of infections, these recent attacks using Trojan.Necurs.A installations are distinctly an issue for the United States. Despite that, other countries also have been targeted, although in much smaller numbers than those for the US. Regardless, no matter where you live, opening an e-mail attachment without confirming its safety first never is wise, and malware experts consider it best to scan any suspicious attachment to block Trojan.Necurs.A, Zeus or other threat from sneaking into your hard drive.
