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:	1/10
Infected PCs:	35

Spyware.SCN-ToolBar can be classified as adware, spyware and a browser hijacker due to its variety of web browser-oriented attacks. Spyware.SCN-ToolBar is very widely distributed and has been detected as one of the most prolific PC threats with respect to home networks, along with other toolbar-based PC threats that are likely to be distributed with freeware programs (such as movie players, file-downloading clients and other media-oriented utilities). Symptoms associated with Spyware.SCN-ToolBar infections include browser redirects to unusual sites and unwanted advertisements, although Spyware.SCN-ToolBar also includes other functions with less obvious symptoms than these. SpywareRemove.com malware researchers recommend removing Spyware.SCN-ToolBar from your PC with anti-malware software that's capable of handling PC threats of Spyware.SCN-ToolBar's level – especially since Spyware.SCN-ToolBar, unlike most forms of adware, is classified as a mid to high-level security risk.

Spyware.SCN-ToolBar – Why Being Number Two in Adware Isn't So Bad

Spyware.SCN-ToolBar was rated the second most prolific PC threat for nonbusiness/government networks in April and June of 2012, just below the MyWebSearch Toolbar. Standard propagation methods for PC threats similar to Spyware.SCN-ToolBar is utilized in bundled install methods wherein a separate (usually freeware) program includes Spyware.SCN-ToolBar or another type of PUP toolbar as either an optional or mandatory service. Careful inspection of installation routines may give you a way to install the original program without installing Spyware.SCN-ToolBar, although SpywareRemove.com malware experts recommend that you try to use software with a clean history of not being associated with Spyware.SCN-ToolBar and other adware.

A Spyware.SCN-ToolBar infection should be readily visible due to its habit of changing error pages and default search engines for Internet Explorer. Spyware.SCN-ToolBar may also display advertisements without your consent via such means as pop-ups, redirects, altered search results or even link-embedding tactics that highlight keywords with links. Other web browsers haven't been confirmed to be affected by Spyware.SCN-ToolBar's attacks, although they have been known to be affected by similar PC threats.

The Problems with Spyware.SCN-ToolBar That You Might Not See

SpywareRemove.com malware research team has also noted that Spyware.SCN-ToolBar includes two other features that, while less obvious than the above examples, are even worse security risks for your PC:

Spyware.SCN-ToolBar will update itself without your consent. While this trait is common for PUPs and adware, Spyware.SCN-ToolBar can be used to broaden Spyware.SCN-ToolBar's features and add even more dangerous attacks to its capabilities. There are no notifications when Spyware.SCN-ToolBar performs an update.
Spyware.SCN-ToolBar can gather information about your web-browsing habits without your consent. Besides being a needless resource hog, this invasive function is also a significant security breach and gives Spyware.SCN-ToolBar its classification as spyware.

Removing Spyware.SCN-ToolBar by the normal means of deleting browser toolbars may be ineffectual at deleting all of Spyware.SCN-ToolBar's components – particularly its spyware features. SpywareRemove.com malware researchers, therefore, recommend deleting Spyware.SCN-ToolBar with the same anti-malware programs that you'd use against all types of spyware.
