Using the VShield Scanner • Display the VShield icon in the Windows system tray. Select the Show icon in the Taskbar checkbox to have the VShield scanner display this icon in the system tray. The particular state in which the icon appears depends on which VShield modules you have enabled. See "Understanding the VShield system tray icon states" on page 92 for details. Double-clicking the icon opens the VShield Status dialog box. Right-clicking the icon displays a shortcut menu.

Click Advanced to open the Advanced Scan Settings dialog box (Figure 4-11). Figure 4-11. Advanced Scan Settings dialog box Heuristic scanning technology enables the System Scan module to recognize new viruses based on their resemblance to similar viruses that the module already knows. To do this, the module looks for certain "virus-like" characteristics in the files you've asked it to scan. The presence of a sufficient number of these characteristics in a file leads the module to identify the file as potentially infected with a new or previously unidentified virus. Because the System Scan module looks simultaneously for file characteristics that rule out the possibility of virus infection, it will rarely give you a false indication of a virus infection. Therefore, unless you know that the file does not contain a virus, you should treat "potential" infections with the same caution you would confirmed infections. The System Scan module starts out without any heuristic scan options active. To activate heuristics scanning, follow these substeps: a. Select the Enable heuristics scanning checkbox. The remaining options in the dialog box activate. b. Select the types of heuristics scanning you want the System Scan module to use. Your choices are: User's Guide 103
