Fairz is an encrypted virus that infects COM and EXE files when they are accessed. It has code to display the following message when a specific file is executed:
This is an [ illegal copy ] of KeyPress virus remover System Halted
Occasionally Fairz will corrupt files while infecting them. Data Fellows anti-virus products will detect such files as "Damaged Fairz-infected file". Such files will be deleted as they cannot be disinfected.
The virus also contains this text: "Eternal Fairz". These texts are not visible when the virus is examined.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
More information on scanning and removal options available in your F-Secure product can be found in the Help Center.
