Ugh! Power off (crash ...)! The hard work is gone. Many people have encountered such a thing, but if you use the word2000, then I tell you, you can make your loss to the minimum (really?). Do not believe: 1. Click the "Save" tab in the Word menu tool "Option" to change the "automatic saving time interval" to 1 minute ("Auto Save Time Interval" is selected first, the default is 10 minutes) In this way, even if there is an unexpected, you lose only 1 minute (of course, the system resources are also big, but the memory is so cheap ...). 2, if you still don't have insurance, then in "Options", select the Save tab, then select the Reserved Backup check box, click the "OK" button, when saving the document later, Word will automatically Save a backup document. To use the backup of the document, just open it, double insurance enough! The above insurance is only sold to the imprisoned typist, and people who are poisoning should look at the following. 3, macro virus is a computer virus stored in a macro in a document or template. Once this document is opened, the macro virus will be activated and transferred to the computer, residing on the Normal template. In this way, all automatically saved documents will "infect" on this macro virus. Word cannot scan the macro virus on the floppy disk, hard disk, or network drive, but when a macro document that may contain a virus is opened, Word can display warning information. If you want the document to contain the macro to be used, you will include a macro when you open a document. If you don't understand the exact source of the document, in order to prevent possible viral infections, it is best not to include the macro when the document is opened. In Word, there are three ways to choose from. The method is: Select the "Macro" command in the tool menu, click the Security command, open the Security dialog, you only need one of them. Protection mode. If you select "High, only the macro signed by the Reliable Source, the unsigned macro will automatically cancel (H)", click the Reliable Source tab, set the reliable source. However, if the shared template "Normal.dot" infected with viruses, Word could not protect themselves. At this time, if you still want to get protected, you need to do the following: Click the "Macro" command of the "Macro" subsequence of "Tool" menu, and then select "Macro position" in the "Macro" dialog box "all activities Templates and Documents, see if "AutoExec", "Autoven", "AutoOpen", "AutoClose", five automatic macros, "AutoExit", if you contain one or more of these automatic macros, this is removed all, so Using Word, you can have no worries, and no function of Word (preferably install virus firewall, and upgrade the virus library). If you don't work, you will be brought to NORMAL.DOT in C: / Windows / Application Data / Microsoft / Templates under DOS. I hope that the above method can give you a little help (who is willing to turn over the things).
