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:	8/10
Infected PCs:	248

Win32/Unruy is a recently-developed classification for PC threats that include traits of both adware and Trojan downloaders. Individual members of Win32/Unruy are often installed by way of outdated JavaScript packages that have unpatched security vulnerabilities. Win32/Unruy is designed to launch every hour of every day (via Scheduled Tasks) and can hide its presence while doing so by using code-injection attacks against normal system processes. While Win32/Unruy can use configuration files to alter its behavior, Win32/Unruy is capable of downloading various PC threats from remote servers, with common payloads including rogue anti-virus programs that are promoted by means of hijacked web pages. Since Win32/Unruy is a danger to your PC that strives to hide itself while facilitating future attacks, SpywareRemove.com malware experts suggest taking all appropriate measures to avoid a Win32/Unruy infection and removing Win32/Unruy with anti-malware software whenever suitable.

Win32/Unruy – a New Attack on an Hourly Basis

Win32/Unruy is designed to run without the consent or even recognition of the persons using their infected PCs, and, accordingly, Win32/Unruy makes use of Windows Scheduled Tasks to launch itself automatically. The default scheduling routine for Win32/Unruy launches this Trojan once every hour on every day of the week, although Win32/Unruy may change this aspect or other aspects of its behavior with configuration files that Win32/Unruy downloads from a C&C server. SpywareRemove.com malware researchers also note that Win32/Unruy has code-injection capabilities that allow Win32/Unruy to hide itself within svchost.exe or iexplore.exe, which will prevent Win32/Unruy from showing up in Task Manager (except in terms of unusual RAM usage, etc.).

Win32/Unruy may download and install other types of malicious files on an arbitrary basis, although SpywareRemove.com malware experts have especially noted Win32/Unruy's involvement in cases of:

The display of irrelevant advertisements with an intent to create artificial traffic-based revenue.
The installation of scamware programs from the FakeSpypro family such as Spyware Protect 2009, Barracuda Antivirus, AV Security Suite or Antivirus .NET. These PC threats will display fake security warnings as a way to persuade its victims to spend money on registration keys for their fraudulent security software.

Why Defeating Win32/Unruy is As Easy as Downloading a Patch

Recent members of Win32/Unruy (such as TrojanDownloader:Win32/Unruy.D) are particularly noted for using JavaScript exploits to install themselves without permission. SpywareRemove.com malware researchers especially recommend that PC users patch JavaScript if they're using versions up to or earlier than v6 update 18, as only updates after that point are protected from current Win32/Unruy attacks. Keeping JavaScript disabled or uninstalled can also be effective at blocking Win32/Unruy – although this can result in minor web-browsing issues due to JavaScript's widespread usage in website design.

Since Win32/Unruy has attack features that are capable of causing varied forms of harm to your PC, including stealing potentially sensitive information, SpywareRemove.com malware researchers recommend that you delete Win32/Unruy ASAP. Win32/Unruy's defensive features also make manual removal an impractical solution, although updated anti-malware scanners shouldn't experience much difficulty in detecting and removing Win32/Unruy.
