5)Multipartite viruses6)Polymorphic viruses7)Stealth virusesFile Virus:-This type of virus normally infects program files such as .exe, .com, .bat. Once this virus staysin memory it tries to infect all programs that load on to memory.Macro Virus: - These type of virus infects word, excel, PowerPoint, access and other data files. Onceinfected repairing of these files is very much difficult.Master boot record files: - MBR viruses are memory-resident viruses and copy itself to the first sector ofa storage device which is used for partition tables or OS loading programs .A MBR virus will infect thisparticular area of Storage device instead of normal files.
