This allows worms to spread extremely quickly, often over a local network and sometimes at an exponential rate. Many worms can self-replicate and self-propagate without any human activation. Thus, worms do not rely on you to trigger them. While they do share some characteristics with viruses, computer worms are self-sufficient programs that don’t require a host program or file.

Once activated, the virus inserts its code into other programs on your device to help copy itself, corrupt your files, damage device performance, and spread to additional devices. The main difference is how they self-replicate, with viruses requiring the help of a host and worms acting independently.Ī virus lays dormant in your system until you execute it or take some other required action, such as enabling macros on an infected DOC file. Viruses and worms both cause damage and copy themselves rapidly.

Viruses infect your system, inserting their code into a program or operating system code and borrowing your computer’s resources to copy and spread. A virus must be attached to a host, such as an executable file or a document. Inheriting its name from its biological counterpart, a computer virus spreads quickly from device to device.
