This life cycle can be divided into four phases: Dormant phase[ edit ] The virus program is idle during this stage. The virus program has managed to access the target user's computer or software, but during this stage, the virus does not take any action. The virus will eventually be activated by the "trigger" which states which event will execute the virus, such as a date, the presence of another program or file, the capacity of the disk exceeding some limit or the user taking a certain action e.

Not all viruses have this stage. The virus places a copy of itself into other programs or into certain system areas on the disk. The copy may not be identical to the propagating version; viruses often "morph" or change to evade detection by IT professionals and anti-virus software.

Each infected program will now contain a clone of the virus, which will itself enter a propagation phase. The triggering phase can be caused by a variety of system events, including a count of the number of times that this copy of the virus has made copies of itself. It can be destructive such as deleting files on disk, crashing the system, or corrupting files or relatively harmless such as popping up humorous or political messages on screen.

EXE or. COM files , data files such as Microsoft Word documents or PDF files , or in the boot sector of the host's hard drive or some combination of all of these. Resident viruses overwrite interrupt handling code or other functions , and when the operating system attempts to access the target file or disk sector, the virus code intercepts the request and redirects the control flow to the replication module, infecting the target.

While virus infected files may be accidentally sent as email attachments , email viruses are aware of email system functions. They generally target a specific type of email system Microsoft's Outlook is the most commonly used , harvest email addresses from various sources, and may append copies of themselves to all email sent, or may generate email messages containing copies of themselves as attachments. Some old viruses, especially on the DOS platform, make sure that the "last modified" date of a host file stays the same when the file is infected by the virus.

This approach does not fool antivirus software , however, especially those which maintain and date cyclic redundancy checks on file changes. They accomplish this by overwriting unused areas of executable files.

These are called cavity viruses.

Because those files have many empty gaps, the virus, which was 1 KB in length, did not add to the size of the file. In the s, as computers and operating systems grow larger and more complex, old hiding techniques need to be updated or replaced. Defending a computer against viruses may demand that a file system migrate towards detailed and explicit permission for every kind of file access. This leaves antivirus software little alternative but to send a "read" request to Windows OS files that handle such requests.

Some viruses trick antivirus software by intercepting its requests to the Operating system OS. A virus can hide by intercepting the request to read the infected file, handling the request itself, and returning an uninfected version of the file to the antivirus software.
