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:	1/10
Infected PCs:	95

Backdoor.win64.zaccess.bt is a component of a ZeroAccess (also known as Max++) rootkit that's specialized for 64-bit Windows environments – although other PC threats associated with ZeroAccess are perfectly capable of infecting 32-bit systems. Backdoor.win64.zaccess.bt attacks have taken a rise in late August/early September 2012, with the majority of victims using anti-malware software to detect Backdoor.win64.zaccess.bt but failing to undertake the proper procedures to remove Backdoor.win64.zaccess.bt permanently. Because ZeroAccess-based PC threats like Backdoor.win64.zaccess.bt are associated with spyware attacks, rogue security programs (such as the Win32/FakeVimes or FakePAV families), malicious browser hijacks and disabled security features, SpywareRemove.com malware researchers recommend that you remove Backdoor.win64.zaccess.bt as quickly as possible. Disabling all related Trojans included in a Backdoor.win64.zaccess.bt infection should allow your anti-malware scanner of preference to remove Backdoor.win64.zaccess.bt without any issues.

Why Backdoor.win64.zaccess.bt Means a Security Nightmare No Matter How Advanced Your PC Is

Besides being designed to attack high-end 64-bit systems, Backdoor.win64.zaccess.bt includes standard compatibility with most versions of Windows, including Windows 7. SpywareRemove.com malware researchers have found various infection vectors for Backdoor.win64.zaccess.bt, most of which utilize some variant of Java, JavaScript or Adobe software exploits to install Backdoor.win64.zaccess.bt in drive-by-download attacks. Keeping the aforementioned software updated should be considered crucial for avoiding the unnecessary presence of vulnerabilities that could be exploited to install Backdoor.win64.zaccess.bt and other ZeroAccess-related forms of malware. Symptoms of these attacks sometimes can include brief occurrences of Java and Adobe-related icons as these programs are loaded to compromise your PC.

ZeroAccess rootkits like Backdoor.win64.zaccess.bt almost always use multiple components that are responsible for a configurable range of different attacks against your PC. In particular, SpywareRemove.com malware experts have expressed especial concern for the frequency of Backdoor.win64.zaccess.bt attacks that are related to anti-security measures, such as blocking the following programs:

Windows Defender – a default anti-spyware scanner that focuses on the detection and removal of malware with information-stealing capabilities.
Windows Update – the default update system that patches Windows for vulnerabilities and exploits.
Windows Firewall – a default utility that blocks unauthorized network access to or from your PC.

Like all members of the ZeroAccess family, Backdoor.win64.zaccess.bt may also be complicit in the installation of other types of malware – such as banking Trojans – and has a high chance of allowing criminals to access your PC through a backdoor exploit.

Battening Down on Backdoor.win64.zaccess.bt's Security Holes

While most anti-malware programs haven't shown any difficulty in detecting Backdoor.win64.zaccess.bt, as a PC threat that uses multiple components and rootkit techniques to support itself, Backdoor.win64.zaccess.bt isn't deleted easily even after Backdoor.win64.zaccess.bt is detected. If you've attempted to remove Backdoor.win64.zaccess.bt, SpywareRemove.com malware experts recommend that you reboot and run a second scan to be certain that Backdoor.win64.zaccess.bt was removed for good.

If Backdoor.win64.zaccess.bt continues to reappear, then it's likely that related ZeroAccess-based PC threats are restoring Backdoor.win64.zaccess.bt as is necessary. With respect to disabling these other segments of a ZeroAccess infection, SpywareRemove.com malware analysts recommend using a USB-based system boot that can provide a sterile scanning environment. Some components of Windows may need to be restored to finish repairing your computer, although proper removal of Backdoor.win64.zaccess.bt with an anti-malware program shouldn't cause any additional damage to your OS.
