Short bio

Floxif.Virus.Fileinfector.DDS  is Malwarebytes’ detection name for a family of viruses detected by Malwarebytes’ Katana engine. The Floxif variants are file infecting virus that also create a backdoor on the affected system.

The detection names are produced by Malwarebytes 4 and Malwarebytes business products. These generic malware detections are due to our new automated signature system called BytesTotal and specifically the DDS engine that are based on Machine Learning technology with 100% autonomous learning which don’t require any human interaction to correctly identify malware. These techniques are part of Malwarebytes’ Katana engine and were developed for automated mass detection of wide ranges of malware and adware.

Type and source of infection

Floxif.Virus.Fileinfector.DDS can change legitimate files into infected files. Then the infected files act as a backdoor, giving the threat actor control over the machine. Floxif.Virus.Fileinfector.DDS can be dropped by other malware or by visiting malicious sites.


After removal of the infected files the system may be missing vital files for programs to run, which often makes a re-format of the system necessary. All removable drives that have been used on an infected system should be checked for the presence of the virus as well.


The Malwarebytes’ Katana engine detects unknown threats as Floxif.Virus.Fileinfector.DDS by using generic detections, Machine Learning, and other Artificial Intelligence techniques to protect users from malware.
