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.

PUP.wxDfast is a technical identification for wxDownload Fast, a download management program that's been noted for several forms of mildly malicious behavior and, thus, labeled as a Potentially Unwanted Program. Besides installing PUP.wxDfast intentionally from the site dfast.sourceforge.net (which some PC security companies have noted to be linked to a subdomain that hosts harmful content), you may also acquire a PUP.wxDfast infection after you install a completely unrelated program that bundles with PUP.wxDfast. PUP.wxDfast is classified as a low-level threat, and while PUP.wxDfast may spam your e-mail contacts with messages that promote itself, SpywareRemove.com malware researchers note that PUP.wxDfast isn't likely to cause significant damage to your PC. However, unwanted installations of PUP.wxDfast are often accompanied by other PC threats, all of which should be removed (like PUP.wxDfast, itself, if applicable) by trustworthy anti-malware products.

PUP.wxDfast – the Helpful Downloader Whose Aid You May Not Want

As download-assistance software, PUP.wxDfast isn't necessarily harmful to your PC and can be used like any other program in cases where its services and features are all desirable.

SpywareRemove.com malware researchers recommend that you avoid general software download sites and download your applications only from direct and reputable sources to avoid any unwanted contact with PUP.wxDfast.

PUP.wxDfast's website has also been noted to include a subdomain with potentially harmful content, and SpywareRemove.com malware researchers suggest using strong browser and anti-malware security while you're interacting with any part of PUP.wxDfast's home site.
