Threat Metric
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.

Napolar is a spyware-for-hire Trojan that specializes in stealing information such as browser-stored passwords and e-mail addresses, but also includes support for additional attacks at the discretion of its criminal user. Although Napolar attacks are flexible, according to whoever happens to be renting a specific instance of this spyware, SpywareRemove.com malware researchers and others in the industry have confirmed that Napolar attacks overall have risen significantly since September of this year. Since Napolar is designed to hide itself while conducting its attacks, deleting Napolar from your computer is a process that almost always requires using appropriate anti-malware products, and SpywareRemove.com malware experts particularly warn that South American nations have been particularly affected by Napolar attacks.
Napolar: the Blindingly Rising Sun of Digital Thievery
Napolar is a new spyware program that first was noted earlier in 2013, but whose numbers have surged remarkably in the past month. Like other spyware and banking Trojan-based PC threats, Napolar is a modular program that's designed to be rented out to other criminals while providing them additional options for expanded features for new attacks. However, modules aside, the central features of Napolar Trojans are oriented around stealing your personal information. All of the information saved by a popular Web browser, e-mail accounts, social networking accounts and FTP accounts are some of the most vulnerable targets of Napolar's thieving tendencies.
Also known as Solarbot, Napolar is suspected to use Facebook spam as its main means of distribution to new victims, and many of its installation files are misnamed so that they look like Facebook-related images. Although Napolar may be considered a global threat, some countries have been targeted more often than others. Of these, malware researchers rate Mexico, the Philippines, Vietnam, Poland and various nations in South America as being at the greatest risk of Napolar attacks.
Setting the Sun on the Napolar Campaign
Although protecting your PC from Napolar spam links is as easy as avoiding obviously suspicious Web links, Napolar, like most other types of spyware, does not have to display any symptoms to implement its attacks once Napolar is installed. Estimated infection rates for Napolar Trojans already are climbing to hundreds daily, and the use of anti-malware programs for removing Napolar can be considered mandatory.
Although the emphasis on Napolar's payload focuses on the informational theft, SpywareRemove.com malware experts also warn that you should be attentive to other dangers related to Napolar infections. Bitcoin-mining functions that may permanently damage your hardware, DDoS attacks that may harm your PC's stability and overall backdoor vulnerability-related antics should be considered possible for any Napolar infection. Since Napolar is modular and may have new components added or removed on a whim, the behavior of one Napolar infection is not necessarily identical to that of a second one.
