A memory virus is a type of computer virus designed to reside and hide within a computer's memory (RAM). It activates and infects files whenever the operating system is running.
Here's a breakdown of key aspects:
-
Residence in Memory: Unlike some viruses that only activate when an infected file is executed, memory-resident viruses stay active in the computer's RAM. This allows them to continuously monitor system activities.
-
Activation and Infection: While resident in memory, the virus can infect other files as they are opened, executed, or copied. This makes them highly efficient at spreading throughout the system.
-
Stealth Capabilities: Many memory viruses employ stealth techniques to avoid detection. They might hide their presence in memory or alter system processes to mask their activity.
-
Impact: Memory viruses can lead to various problems, including:
- Data corruption
- System instability
- Slow performance
- Spread of infection to other files and systems
In essence, a memory virus is a persistent and stealthy threat that lives in your computer's active memory, constantly seeking opportunities to infect other files and potentially compromise your system.
