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.

Recently confirmed for its attacks against Asian countries including Vietnam, China and Taiwan, Keyboy is a combination of backdoor Trojan and spyware, with general-purpose security-reductive attacks coupled with functions intended for stealing information from three of the world's most popular web browsers. Although Keyboy is perfectly capable of being a threat to any casual PC user, SpywareRemove.com malware experts have observed that Keyboy's pattern of infections – distributed through carefully-targeted e-mail messages – sync up well with the concept of Keyboy attacking specific industry companies and government agencies. A good combination of self-education on internet safety and updating your software will block Keyboy's current infection vectors, and at least half of all major anti-malware brands have developed definitions for removing Keyboy from your computer.
How an E-mail Unlocks All of Your Private Info
Keyboy, named for one of the text strings found in some of its earliest-analyzed samples, continues the general theme of backdoor Trojans being used for espionage against corporations and government institutions alike, with many attacks targeting educational facilities and employees of telecommunications companies. Like most attacks themed thusly, Keyboy's attacks begin with e-mail messages that are designed to include content that appeals to the reader. Opening an enclosed file attachment subjects the PC to an old (but still effective) exploit that installs Keyboy automatically.
Patching Microsoft Office software is the easiest method of preventing Keyboy's exploits from taking place, and is, regardless, recommended by SpywareRemove.com malware researchers as a standard security measure. Examples of other PC threats that also use similar installation techniques to Keyboy include Backdoor.Makadocs, BKDR_PLUGX.SME, BKDR_POISON.DOC, Enfal and most document-based Trojan droppers (like TROJ_ARTIEF.JN).
Having successfully infected your computer, Keyboy will attempt to steal information directly from Internet Explorer and Firefox, including login details like passwords. However, before Chrome fans start to feel safe, it should also be stressed that Keyboy installs a second component – a specialized keylogger – that also steals information from Chrome.
Shutting Your Computer Door to Keyboy's Pilfering
Despite its competence at stealing information, Keyboy shouldn't be thought of as just spyware since Keyboy also includes functions that SpywareRemove.com malware researchers warn can be used for other attacks. These attacks can include installing other malware, uploading files from your computer, issuing commands to your PC from a remote server and similar backdoor-based security issues.
Based on past statistics gathered by SpywareRemove.com malware analysts, opening an unusual e-mail attachment probably is one of the quickest ways to infect your PC, and Keyboy is not kind enough to display symptoms to indicate its presence. You should act to remove Keyboy as quickly as possible, but doing so without appropriate anti-malware tools runs the risk of failing to delete all of Keyboy's components... or other PC threats installed by Keyboy.
