Techopedia Explains Mobile Code

Malicious mobile code infects hard drives, resulting in rapid code replication. Malicious mobile code often attaches to Web software requiring a plug-in for download (such as ActiveX, Flash or JavaScript) or is embedded in an infected website. For example, a user visits a website to download seemingly harmless content, like a song. If the song is infected and then executed, the infection spreads to the user’s computer.
