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.

Tuvaro is free browser add-on, which is advertised via other free software downloads. Once installed on a compromised PC, Tuvaro will add the Tuvaro Toolbar, change the default homepage and search engine of the hacked web browser to tuvaro.com. The Tuvaro Search Bar will display advertisements and sponsored links in victimized search results, and may gather search terms from search queries of an affected Internet user. Tuvaro Toolbar gets on the vulnerable computer after the PC user has installed another free software product or add-on that had bundled into their installer Tuvaro Toolbar. For example, when the computer user installs vPlay, he/she will also agree to change the default browser homepage and default search engine to tuvaro.com, and install the Tuvaro Toolbar. However, when the computer user uninstalls vPlay from the computer, the web browser's default settings will not be restored. This means that the PC user will have to remove Tuvaro Search from the favorite web browser manually.
