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.

Backdoor.Betwem is a deceptive backdoor Trojan horse that may end up on a vulnerable system that does not have many security protection measures in place. When loaded on a computer, Backdoor.Betwem is apt to running in the background where it could go undetected for a long time while it performs unknown malicious actions. The backdoor functions of Backdoor.Betwem may allow remote attackers to connect to an infected system. In doing so, remote hackers may be able to steal or gather data from the infected computer’s hard drive and use it in cases that lead to identity theft or other serious issues. Putting a rest to these potential issues is a situation that may require complete removal of Backdoor.Betwem, which can be done through use of an antimalware application.
