Threat Scorecard
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.

BlockTheAds is an application developed by Webpick Internet Holdings. The purpose of this software is to enhance the browsing experience of PC users by blocking unwanted advertisements, and, therefore, improve the browser's performance and reduce clutter. The tool may sound pretty handy for now, but its publishers may have forgotten to mention that their software is ad-supported. BlockTheAds may prevent websites from showing their advertisements, but it won't solve the issue. Instead, it will insert its ads into the place of the original ones, therefore robbing the website's authors from their revenue. This technique is very questionable, and our security researchers recommend that you stay away from BlockTheAds, or any other product coming from Webpick Internet Holdings.
The company is renowned for its adware, and BlockTheAds isn't any different. As soon as you install this app, it may inject BlockTheAds ads in your web browsers. Unfortunately, injecting ads isn't the only thing this frustrating application can do. It may also work in the background and collect data regarding your browsing habits. If this software is installed on your PC, we advise you to use a legitimate anti-malware solution that should easily get rid of the BlockTheAds adware.

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.- Agent.OCD
