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.

SW.Booster is a component of Installerex, a utility that third parties use to distribute adware and other Potentially Unwanted Programs throughout the Web. Malware researchers currently categorize SW.Booster as a Potentially Unwanted Program. Removing SW.Booster also may require the removal of adware and other applications affecting your browser, during which you should be happy to use anti-adware tools as they're needed.
The Mastermind Behind Your Browser's (Unwanted) Add-Ons
Malware researchers previously examined Installerex, which is a general installation application that may be used for a range of different programs. However, its history especially is filled with the promotion of adware, browser hijackers and other kinds of PUPs that change your browser to your detriment – and their profits. SW.Booster is a secondary PC threat that may be installed along with Installerex's main programs.
SW.Booster also is distributed in other variants, presumably to prevent you (or PC security companies) from identifying SW.Booster immediately. Malware experts have been able to identify the following variations on SW.Booster:
- Ws-Enabler
- Sk-Enhancer
- OptimizerPro
The add-ons benefiting from SW.Booster's dubious protection typically redirect your online searches, inject advertisements into your browser or perform other acts that are drawbacks to your Web-surfing security and enjoyment. Although these programs only are categorized as PUPs, malware experts do recommend their removal, along with SW.Booster and Installerex.
Boosting Your Browser out of the SW.Booster's Influence
There are few ways of acquiring a SW.Booster installation without making some mistakes in your file-downloading habits, such as trusting unsafe websites or links from suspicious sources. Along with watching your own online behavior, malware experts also suggest scanning files that could include Installerex, SW.Booster or other PUPs. Security products whose scope includes adware and threats may be able to identify these programs before they've installed software onto your computer and, hence, negatively impacted your Web browser. Browsers affected may include Chrome, Firefox and Internet Explorer, but other browsers shouldn't be excluded.
SW.Booster may pretend to provide benefits to your browser, but its tactic should be easily seen through by anyone who knows even a slight amount about computers. Considering the drawbacks implicit in letting other programs control what's on your system, malware experts always find removing SW.Booster to be the right thing to do.
