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.

The Blekko search engine distinguishes itself by prioritizing spam-free search results. As a community-based search engine, it employs both a dedicated crawler and a human review process to combat spam, providing users with reliable search outcomes.
Addressing Redirect Issues
Despite its commitment to spam-free results, some users encounter unwanted redirects to Blekko.com. This issue is often linked to the installation of the Blekko toolbar, a browser plug-in that modifies settings without user consent, changing the homepage and default search engine to Blekko.com.
Source of Redirect Problems
Users who find themselves unintentionally redirected to Blekko.com may have unknowingly installed the toolbar, often bundled with free software downloaded from the Internet. It's crucial for users to be vigilant during software installations, as free downloads can include additional browser extensions, such as the Blekko toolbar.
Understanding Blekko Toolbar Features
While the Blekko toolbar itself is not inherently malicious, it offers quick launch buttons for social networks and weather forecasts. However, the toolbar is commonly bundled with the Anti-phishing Domain Advisor, a browser add-on known for displaying unwanted ads and coupon offers.
A common strategy for monetization involves bundling free software with Internet browser add-ons, potentially leading to the involuntary installation of the Blekko toolbar. To avoid such instances, users should exercise caution and attentiveness during the download and installation of free software.
Despite concerns about redirects, it's essential to recognize that Blekko is a legitimate search engine, offering safe and credible results for daily Internet searches. Users who willingly install the Blekko toolbar and are aware of redirects need not take further action.
Removal for Unwanted Installations like Blekko
For users who have inadvertently installed the Blekko toolbar and are bothered by redirects to Blekko.com, a removal guide is available to help eliminate the issue. Taking proactive steps can restore the desired browser settings and enhance the overall online experience.
