EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Popularity Rank: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

BestWeb is an aggressive adware extension that is compatible with Internet Explorer, Firefox and Google Chrome. This dubious program has one single purpose – to inject annoying advertisements in the user's Web browser. The ads that BestWeb displays may include misleading links to potentially harmful Web destinations, or fake raffles whose purpose is to collect information from all visitors. The BestWeb browser extension doesn't rely on traditional distribution techniques, and this adware doesn't have an official Web page or download source. Instead, its authors may use software bundling to distribute it, and they may utilize confusing installation instructions to trick users into agreeing to install BestWeb.
Some software bundles may promote BestWeb as a useful Web browser tool that can enhance the user's Web browsing experience. However, BestWeb's promises aren't reliable, and we assure you that you will not notice any positive changes if you opt to install BestWeb. As soon as this adware receives permission to install itself on a user's computer, it may start to modify the Web browser's behavior by displaying advertising overlayed on top of most websites the user visits. Apart from harassing users with advertisements, the BestWeb extension also may collect their Web browser usage statistics which is a major privacy concern. If your Web browser is filled with 'BestWeb Ads' or if you notice this extension on your computer, you should remove it as soon as possible. The removal of BestWeb should be carried out with the assistance of a reputable anti-malware solution that can fully remove all of the adware's components.

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- Kryptik.BH
