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:Win32/WipMBR.A is a Trojan dropper that installs Trojan:Win32/WipMBR.B, a PC threat that causes permanent damage to Windows and prevents your PC from loading. Given the unusually destructive nature of Trojan:Win32/WipMBR.A's payload, a Trojan:Win32/WipMBR.A infection may be hard to miss, but will require you to repair your operating system before you can even begin to delete Trojan:Win32/WipMBR.A or Trojan:Win32/WipMBR.B. Therefore, SpywareRemove.com malware researchers recommend that you do your utmost to prevent a Trojan:Win32/WipMBR.A infection in the first place with appropriate online safety habits and anti-malware security programs.
Trojan:Win32/WipMBR.A: Going 'Old School' on Your Master Boot Record
Even though malware has evolved to become extraordinarily sophisticated, recent schools of thought for malware development tend to emphasize the potential for profit through subtle attacks, such as banking Trojan attacks that insert malicious content into the web pages of bank websites. Trojan:Win32/WipMBR.A stands in sharp contrast as a throwback to an elderly style of malware, wherein the foremost goal was to annoy the PC user or actually destroy the PC itself.
Taken individually, Trojan:Win32/WipMBR.A's primary responsibility is the installation of a related Trojan, Trojan:Win32/WipMBR.B. SpywareRemove.com malware researchers have yet to find the propagation routes for Trojan:Win32/WipMBR.A, although they do note that Trojan:Win32/WipMBR.A is a recently-identified PC threat that's still in distribution as of this month of 2012. Trojan:Win32/WipMBR.A is compatible with 32-bit and 64-bit versions of Windows, and includes slightly different payloads for each version of that OS, although the consequences are, in the end, identical.
What Happens When Trojan:Win32/WipMBR.A's Payload Reaches the End of Its Fuse
After Trojan:Win32/WipMBR.A has installed Trojan:Win32/WipMBR.B, it sets a job scheduled to launch Trojan:Win32/WipMBR.B immediately. Trojan:Win32/WipMBR.B proceeds to overwrite the MBR and other Windows components with fragmented JPEG data. This causes system failure and will result in Windows (which is immediately rebooted by Trojan:Win32/WipMBR.B) being unable to load.
If it's inconvenient for you to repair your OS with its source materials right away, you can also attempt to boot your PC from a USB drive-based OS. The original operating system will need to have its damaged files restored from a clean source before Trojan:Win32/WipMBR.A or related PC threats can be deleted safely. On the bright side, most other files and programs on your PC (such as text documents, pictures and audio files) should be undamaged after you repair the OS issues caused by Trojan:Win32/WipMBR.A's payload.
SpywareRemove.com malware experts also stress that Trojan:Win32/WipMBR.A has displayed a limited ability to distribute itself through local networks (worm-style propagation) by copying itself to vulnerable locations and then installing itself automatically. You should prevent other PCs from accessing network-shared folders or drives on your PC if you suspect any possibility of a Trojan:Win32/WipMBR.A infection.
Aliases of Trojan:Win32/WipMBR.A include TR/Crypt.FKM.Gen, W32/Dropper.gen8!Maximus and W32/Troj_Generic.DKYIW.
