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.

Threat Level:	10/10
Infected PCs:	35

Windows Proofness Guarantor is a rogue security program that's cloned from preexisting threats like Windows Necessary Firewall. Computers that are infected with Windows Proofness Guarantor may seem to be attacked by a variety of different threats, but all of these threats are created by Windows Proofness Guarantor as 'proof' of Windows Proofness Guarantor's security features. Since Windows Proofness Guarantor's security functionality is a mirage and Windows Proofness Guarantor's negative attributes are significant, you shouldn't wait one second to remove Windows Proofness Guarantor from your PC. The likelihood of related Trojans being present and the possibility of sophisticated attacks like browser hijackers makes an anti-virus program useful for deleting Windows Proofness Guarantor without side effects.

Windows Proofness Guarantor: the Fake Microsoft Security Essentials Alert Program That Guarantees Only Trouble

Windows Proofness Guarantor is close kin to other rogue security programs like Windows Inviolability System, Windows Antivirus System, Windows AV Component and Windows Microsoft Guardian. As of June 2011, Windows Proofness Guarantor is a new clone of these other rogue security programs but still uses the same, old attacks against your PC.

Windows Proofness Guarantor infects most computers with the help of a secondary threat, the Trojan known by the name of Fake Microsoft Security Essentials Alert. Fake Microsoft Security Essentials Alert ingeniously will warm you about a fake Trojan that being on your computer before installing a real threat: Windows Proofness Guarantor or a clone program.

This deceptive installation process may show off any number of warnings to convince you that the installation of new software is necessary. One possibility includes this example:

Microsoft Security Essentials Alert
Potential Threat Details
Microsoft Security Essentials detected potential threats that might compromise your private or damage your computer. Your access to these items may be suspended until you take an action. Click 'show details' to learn more.

Despite Fake Microsoft Security Essentials Alert's claims, Windows Proofness Guarantor and similar rogue security programs have no real threat-detection or removal functions. Nonetheless, they'll all do their best to trick you into thinking that they do have security-related functions. To this end, other fake messages may come from Windows Proofness Guarantor itself and can include fake alerts like the following:

Warning!

Viruses: Backdoor.Win32.Rbot

In spite of these errors, a general appearance of being a legitimate program, and even the use of a security-grading system and the Windows logo, Windows Proofness Guarantor is a fake security program that can't offer any of the functions that it tries to sell to you.

The Real Windows Proofness Guarantor Guarantee – That Your PC Will Malfunction
