This is the detection for the Neshta family of viruses, targeting Windows systems which has been around since at least 2010.
Virus.Ramnit is a generic detection for files that are infected with the Ramnit malware.
Malwarebytes protects users from Virus.Ramnit by using real-time protection.
Malwarebytes can remove the infected files. However, if the infection has been active for a while, this usually leaves the affected system unusable, since necessary files may have been infected and removed. If this is true, we recommend making a backup of important files that do not have the EXE, DLL, and HTML extensions and reformatting.
