Worms are a self-replicating type of malware (and a type of virus) that enter networks by exploiting vulnerabilities, moving quickly from one computer to another. Viruses can also attack data: they can disrupt access, corrupt, and/or destroy your data. Typically, the host program continues to function after the viral infection, but some viruses overwrite entire programs with copies of themselves, which corrupts and destroys the host program altogether. Once a user opens the infected file or program, the vicious cycle repeats itself all over again. How Does a Computer Virus Spread?Ī virus spreads when the infected file or program migrates through networks, file collaboration apps, email attachments, and USB drives. It continues to replicate and spread by attaching replicas of itself to other files and applications in the system. When the infected application or file runs in the computer, the virus activates and executes in the system. Once the virus attaches itself to that file or program (aka, the host), they’re infected.
