Threat Types

Threats to your computer system, data, and identity come in many different forms, a few of the most common are listed as follows:

Viruses:

A virus is a self-replicating program that is designed to damage or degrade the performance of a computer. A virus is replicated by being copied or by initiating its copying to another program, computer boot sector or document. Viruses can be classified into four different categories as follows:

File Infector

A File infector virus when executed on a system will seek out other files and insert its code into them. The programs with .EXE and .COM extensions are the most commonly targeted, but a file infector virus can target any executable file.

This infection is most commonly distributed via compromised networks, over the web via drive-by, or from a corrupted media (CDRW, flash media).

Process Explorer

Process Explorer shows you information about which handles and DLLs processes have opened or loaded. The Process Explorer display consists of two sub-windows.
The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.
