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.

KeyStart (aka Backdoor.KeyStart) is a backdoor Trojan designed to coerce a user into purchasing rogue software. Backdoor.KeyStart is installed deceptively after infiltrating the user's PC via a video codec or a corrupt email attachment. KeyStart is advertised via popup alerts that pretend to be online scanners. Backdoor.KeyStart then prompts the user to download and install KeyStart as a solution to fixing the user's computer. The scanners are fake and can be ignored.
KeyStart will start every time your computer is rebooted. It will then scan your computer and state that your computer can run more efficiently if you purchase Backdoor.KeyStart and let it optimize your computer. KeyStart can make your computer slower and run less efficiently. Backdoor.KeyStart is particularly damaging once it has embedded itself within the system. KeyStart is a high priority security risk and computer experts recommend removing it using a reliable antivirus program to make sure your PC is threat free.
