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:	9/10
Infected PCs:	11

JS:Redirector-B is a browser hijacker that exploits JavaScript vulnerabilities to change the web page content that your browser displays. These attacks may be used to alter preexisting web pages, force you to be exposed to malware-downloading attacks or even monitor and steal confidential information. However, most browser hijackers like JS:Redirector-B infections are used to redirect you to semi-harmless sites for the sake of profiting from the increase in traffic or artificial clicks on advertisements. SpywareRemove.com malware researchers also warn that JS:Redirector-B is unlikely to be the sole PC threat on a computer, since JS:Redirector-B often is installed by various types of Trojans, including some PC threats with botnet and backdoor capabilities. Alone, JS:Redirector-B is a minor but noticeable security hazard, but any signs of JS:Redirector-B should be reacted to with anti-malware scans that can delete JS:Redirector-B and any other malware that may be accompanying a JS:Redirector-B infection.

When Advertisements Aren't Just Harmless Commerce... and What JS:Redirector-B Has to Gain from Them

JS:Redirector-B is a browser hijacker that can be used to expose you to virtually any type of malicious or unwanted online content. Nonetheless, the majority of JS:Redirector-B attacks compromise of the insertion of advertising content into web pages that normally lack such advertisements; for example, additional advertisements may display at the top of Google search results. Similar symptoms that JS:Redirector-B may display include the presence of pop-ups and keyword-based links to other sites. These attacks allow criminals to gain profit from your nonconsensual traffic and may contain harmful content.

JS:Redirector-B also is associated with significant performance problems and the presence of other forms of malware, such as rogue file cleaners like Drive Cleaner or Win Antivirus. If you see unusual pop-up alerts, scans from unrecognized security programs or other unusual behavior, PC threats associated with JS:Redirector-B are likely to be the cause. SpywareRemove.com malware experts note that this is especially relevant due to JS:Redirector-B's potential for forcing your browser to load web pages with drive-by-downloads. Drive-by-download exploits can install scamware and other PC threats automatically, without permission and without any symptoms.

Getting Headed in the Right Direction After JS:Redirector-B Strikes

Along with its active attacks, JS:Redirector-B may also remain open in PC's memory regardless of your browser usage or lack of such. SpywareRemove.com malware analysts suggest using Safe Mode to disable JS:Redirector-B first, and loading your OS from a USB device if Safe Mode fails to disable JS:Redirector-B. Since JS:Redirector-B may be used to steal private information without showing any visible signs of the attack, you should be cautious about entering passwords and other private information through your browser while JS:Redirector-B is open.

Anti-malware programs can be used to delete JS:Redirector-B and any other malware on your PC if you do see any of the symptoms of a JS:Redirector-B infection. However, not all JS:Redirector-B infections display symptoms, and SpywareRemove.com malware researchers recommend that you keep anti-malware programs monitoring your computer semi-regularly to protect against attempted JS:Redirector-B installations and other JS:Redirector-B-related attacks.
