Resident viruses are a category of malicious computer virus. A resident virus attaches to the memory of your computer and remains hidden. When the memory that the virus is attached to triggers, the virus activates simultaneously. The virus will then move to infect a file or disk. The most common type of resident virus is the boot virus, which activates when the computer starts. The most effective protection against resident viruses is an up-to-date antivirus program.
