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.

Although Trojan.Zeroaccess.B is nearly-indiscernible from Trojan.Zeroaccess on 32-bit Windows computers, SpywareRemove.com malware researchers caution that this lack of originality doesn't indicate that Trojan.Zeroaccess.B is anything less than a high-level threat to your computer's safety and privacy. Trojan.Zeroaccess.B contains both dropper and backdoor functions that allow Trojan.Zeroaccess.B to download and install other PC threats, and rootkit functions that allow Trojan.Zeroaccess.B to easily-dodge basic detection and removal techniques. Deleting Trojan.Zeroaccess.B should always use appropriate anti-malware programs, although programs that aren't equipped with recent threat databases may be unable to detect Trojan.Zeroaccess.B, which was widely-identified only late in December of 2011.

Trojan.Zeroaccess.B: Making Headway with Every Version of Windows That It Can Grab

Trojan.Zeroaccess.B is designed to attack both 64-bit and 32-bit versions of Windows and is capable to successfully-infect Windows 95 up to at least Windows Vista. Trojan.Zeroaccess.B's behavior includes some minor additional features for 64-bit systems, as SpywareRemove.com malware analysts note in the following list of its functions:

In 64-bit computers, Trojan.Zeroaccess.B will create additional folders for malicious files in sub-folders of the Windows directory.
Trojan.Zeroaccess.B also installs and loads harmful .dll files.
A component of Windows Firewall that monitors networking is then halted; you may be able to observe this by noting a lack of the MpsSvc.exe process in Task Manager.
Your Windows Registry is then altered to change system settings for reduced security.
Afterwards, Trojan.Zeroaccess.B will download and install other PC threats that will attempt to hook themselves into normal system processes – in some cases, this can include processes for popular web browsers like Chrome or Internet Explorer.
Last of all, Trojan.Zeroaccess.B opens a backdoor that can allow criminals to control your PC, view files, or conduct other attacks (such as botnet-based DDoS attacks). This may also allow other PC threats, including Trojans, spyware or browser hijackers to be installed.

Sifting Through Your Computer's Memory for Trojan.Zeroaccess.B

Because components of Trojan.Zeroaccess.B and related PC threats can attach themselves to normal files and processes, SpywareRemove.com malware experts discourage any attempts to find or remove Trojan.Zeroaccess.B on your own. In ideal circumstances, a total scan of your PC via anti-malware software should be able to detect and delete all components of Trojan.Zeroaccess.B before harm to your PC results.

However, rootkit functions like those that are used by Trojan.Zeroaccess.B may also require extra measures to be disabled before you can delete Trojan.Zeroaccess.B. SpywareRemove.com malware researchers warn that you may be required to disable System Restore, boot into Safe Mode or boot Windows from an external source before you can shut down Trojan.Zeroaccess.B long enough to remove Trojan.Zeroaccess.B. Although the removal of Trojan.Zeroaccess.B is far from an easy job, tolerating Trojan.Zeroaccess.B – and the potential web browser hijacks, spyware attacks and other consequences – can definitively be said to be the worse option.
