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.

Trojan.Patchep!sys is a heuristic detection for PC threats that infect native Windows components to enable the easy execution of other PC threats, such as spyware. Since Trojan.Patchep!sys, like similar Trojans such as Trojan Horse Patched_c.LYT, Trojan horse Patched_c.LZE or Trojan Horse Patched_c.LYU, will most likely be detected as an infection for services.exe, you should never try to delete the 'host' file of a Trojan.Patchep!sys infection due to the mandatory nature of this file for the smooth operation of Windows. Competent anti-malware software should be able to detect and remove Trojan.Patchep!sys, which can be injected into active memory processes and, thus, leave few obvious footprints of its presence on your PC.

Trojan.Patchep!sys: One More Reason You Might Be Seeing Frequent System Alerts

Although Trojan.Patchep!sys isn't guaranteed to show symptoms of its own besides very minor discrepancies in your PC's memory usage, most victims of Trojan.Patchep!sys infections first become aware of the fact after receiving warnings from installed anti-malware programs. These programs may display warning messages on a minute-by-minute basis, since Trojan.Patchep!sys will be injected into the memory processes of unrelated programs regularly. Under these circumstances, even if your anti-malware programs appear to be able to remove Trojan.Patchep!sys, it's common for related PC threats (such as Alueron rootkits) to reinstall Trojan.Patchep!sys after its deletion, and you should always try to disable all forms of malicious software before you scan your computer.

Trojan.Patchep!sys's singular goal is to launch other PC threats, and while its payload isn't hardcoded within its body, Trojan.Patchep!sys is particularly associated with Infostealer.Gampass.
