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.

You should think twice before you give permission for the installation of Advanced Calendar. This application comes with a range of annoying side effects, most noticeable of which are the newly generated advertising materials. The negative user feedback is the reason the computer experts label Advanced Calendar as a Potentially Unwanted Program (PUP). The most popular distribution strategy of this questionable tool is also rather misleading. In almost all cases, it arrives in the systems of its clients together with another free application. This approach is called "bundling", and is so efficient because the users often conduct the installation of freeware through the "Quick" menu. It usually doesn't provide detailed data about the suggested bonus elements, and, as a result, some users may load Advanced Calendar unintentionally. This program, which has been developed by Meixian Xie, allows its clients to schedule their daily tasks. You can achieve it with the help of the integrated Windows calendar as well, so the benefits of keeping Advanced Calendar are questionable at best. What annoys some users is that the PUP inserts pop-ups, banners and sponsored videos in Google Chrome, Mozilla Firefox and Internet Explorer. These ads may slow down the operating speed of the web clients. If your PC is not so powerful, you may experience occasional freezes and crashes as well because the commercial materials use some of the system resources. The ads are related to your browsing history and may be tempting, but you should not click on them. They may transfer you to fraudulent or potentially harmful domains. If you feel that Advanced Calendar comes with more cons than pros, you should delete it with a dedicated anti-malware product.
