  • Viruses resident (in English: Resident viruses), which is that hides itself in random access memory (in English: RAM) for the system, he can count the virus to infect new files and programs, even if the original file is deleted for the virus, usually the virus begins this work when activating the operating system (English: Operating system) program or start a particular job.
