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.

Virus:Win32/Virut.gen!AO is a virus, which enables cybercriminals to obtain access to a compromised PC. Virus:Win32/Virut.gen!AO drops and executes malevolent files and resricts a target computer user from visiting security-related websites. Virus:Win32/Virut.gen!AO is distributed through corrupted networks and removable drives such as USB sticks, floppy disks or flash card readers. Virus:Win32/Virut.gen!AO searches for all the removable drives on the corrupted PC from drive D:\ to Z:\. When Virus:Win32/Virut.gen!AO is finds a removable drive, it installs a copy of itself with a randomly created filename. Virus:Win32/Virut.gen!AO can destroy some corrupted files and does not allow to repair them. Virus:Win32/Virut.gen!AO blocks programs from operating appropriately or makes them crash when executed. Virus:Win32/Virut.gen!AO is a polymorphic file infector, which embeds a malevolent code into every .EXE and .SCR file that it finds on the attacked PC. While being executed, Virus:Win32/Virut.gen!AO embeds a malevolent code into the 'WINLOGON.exe' process. Virus:Win32/Virut.gen!AO creates the registry entry so that the virus is embedded on the authorized program list of the firewall.
