There are other harmful computer programs that can be part of a virus but are not considered viruses because they do not have the ability to replicate. These programs fall into three categories: Trojan horses, logic bombs, and deliberately harmful or malicious software programs that run within a Web browser, an application program such as Internet Explorer and Netscape that displays Web sites.
A Trojan horse is a program that pretends to be something else. A Trojan horse may appear to be something interesting and harmless, such as a game, but when it runs it may have harmful effects.
A logic bomb infects a computer’s memory, but unlike a virus, it does not replicate itself. A logic bomb delivers its instructions when it is triggered by a specific condition, such as when a particular date or time is reached or when a combination of letters is typed on a keyboard. A logic bomb has the ability to erase a hard drive or delete certain files.
Malicious software programs that run within a Web browser often appear in Java applets and ActiveX controls. Although these applets and controls improve the usefulness of Web sites, they also increase a vandal’s ability to interfere with unprotected systems. Because those controls and applets require that certain components be downloaded to a user’s personal computer (PC), activating an applet or control might actually download malicious code.
You don’t have to keep an open and updated list of recent documentsif you don’t want to.As with other Start menu options, right-clicking the Start button and selecting Properties allows you to configure the My Recent Documents item that appears on the Start menu. You can choose to show all your recent documents or show none at all, or to manually clear the list yourself. If you want the list to be cleared automatically when you log off, you have to open the Group Policy Editor, locate the appropriate setting, and enable the option to clear the My Recent Documents history on exit. Here’s how:
1. Click Start | Run and type gpedit.msc. Click OK.
2. Under Local Computer Policy, expand User Configuration | Administrative Templates and select Start Menu And Taskbar.
3. Scroll down about halfway through the list and double-click ClearHistory Of Recently Opened Documents On Exit.
4. Select Enabled, and click OK.
You can also turn off the My Recent Documents feature permanently, which may be a better solution. If you prefer not to use the Group Policy Editor, just right-click Start, choose Properties | Customized | Advanced, and uncheck List My Most Recently Opened Documents.
