A multipartite virus is a computer virus that infects and spreads in multiple ways. The term was coined to describe the first viruses that included DOS executable files and PC BIOS boot sector virus code, where both parts are viral themselves. Prior to the discovery of the first of these, viruses were categorized as either file infectors or boot infectors. Because of the multiple vectors for the spread of infection, these viruses could spread faster than a boot or file infector alone. Ghostball was the first multipartite virus, discovered by Fridrik Skulason in October 1989. == Symptoms == Multipartite viruses tend to work fast and some of the infections are subtle and are unnoticed. The following symptoms, may indicate an infection from a multipartite virus: * Drive controllers will no longer be present in Device Manager〔 * Constant notification about virtual memory being low〔 * Screen content will appear as if it is melting〔 * Applications and files sizes continually change〔 * Hard drive reformats itself〔 * Word processing document extensions modified from DOC to DOT〔 * Program may or may not execute, and will experience much longer loading times 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Multipartite virus」の詳細全文を読む スポンサード リンク
