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:	5/10
Infected PCs:	81

Win32/Dorkbot.D is a worm and spambot that utilizes the resources of infected computers to flood websites with illegitimate traffic. Variants of Win32/Dorkbot.D may also be instructed to perform other actions, such as disabling your computer's security, installing other types of malicious software or stealing private information. Although Win32/Dorkbot.D was first reported in late May of 2011, Win32/Dorkbot.D should still be considered a potential threat to any Windows PC. To protect your PC from possible Win32/Dorkbot.D attacks, SpywareRemove.com malware analysts advise that you be very attentive to the security of your network-shared folders and any removable drive devices that you may use on a regular basis. Removing Win32/Dorkbot.D should be undertaken only by suitable anti-malware programs, since Win32/Dorkbot.D is capable of duplicating itself and will try to avoid manual deletion.

Win32/Dorkbot.D – More Serious Than Its Name May Lead You to Think

Although Win32/Dorkbot.D is capable of infecting any PC that has significant contact with a system that Win32/Dorkbot.D has already infected, Win32/Dorkbot.D's distribution prioritizes computers that are in the United States (due to the relative trustworthiness of US IPs). SpywareRemove.com malware experts note that an original Win32/Dorkbot.D infection may occur when you have contact with a malicious site or a P2P file that's infected with Win32/Dorkbot.D, but afterwards, Win32/Dorkbot.D has additional methods of propagation. These include:

Spreading through networks. Win32/Dorkbot.D can create copies of itself in any location that's shared over a network. Any PC that tries to access these shared locations will be infected with Win32/Dorkbot.D by default.
Spreading via removable drive devices. Thumb drives and other types of removable devices can also be infected by Win32/Dorkbot.D automatically, causing any PC that also uses this device to be infected in turn.

In both cases, Win32/Dorkbot.D doesn't require any other interaction, such as launching a file, to spread itself, and you may not even see visible signs of Win32/Dorkbot.D's installation.

What Happens When This Dork Hangs Around Your PC

SpywareRemove.com malware research team has found that, although Win32/Dorkbot.D may be instructed to perform different attacks, its primary purpose is to use an infected PC to flood websites with excessive traffic. These DDoS attacks shut down websites and are considered criminal. In addition, Win32/Dorkbot.D's functions may also have other side effects for your PC, including poor system performance, slowdown, crashes and general instability.

These problems, however, will cease once Win32/Dorkbot.D itself has been removed from your PC. Like most types of malicious software, Win32/Dorkbot.D has been noted to launch itself automatically, and you should consider Trojan:win64/Sirefef.E active, until you've used specific measures to disable Win32/Dorkbot.D's startup process.

Win32/Dorkbot.D is also known by the alias Win32/Dorkbot!Lnk and may be detected under that label by certain types of anti-malware applications. Under ordinary circumstances, you should never attempt to remove Win32/Dorkbot.D without assistance from such software, since Win32/Dorkbot.D is capable of copying itself and will do so to avoid being deleted.
