What methods can make your computer more secure?

Computer security Whether you are still the life of your computer or the files in your computer, computer security is not something that can be done overnight. If you want to maintain computer security, you must consciously guard against him. Is there any way to make the computer safer?

1. Turn off the dangerous process

First of all, we must enter In the service, go and see what dangerous system process is open. See the comment? "Allow remote operation of the registry", turn it off (Remote Registry) I point to the AT command, also off (Task Scheduler), so that the intruder can use it to start the Trojan.

Open the registry, enter HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrent_VersionWinlogon on the right to find a key value DontDisplayLastUserName, then change to 1, if it does not exist, you will create a new one!

2, it is necessary to prevent IPC empty connection !

Ok, let's go to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsa and find this primary key, restrictanonymous, to change it to 1.

If you change to 2, some programs may not work, so generally change to 1.

3, we will modify the default port of 3389

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal ServerWinStationsRDP-Tcp come here, find PortNumber, decimal is 3389, you can change it to other 4 numbers, I Changed to 1314, so the intruder can not 3389 invade your computer.

4, enter cmd, run net share and net user

See what shared and suspicious user names. Administrator and Guest are the defaults of the system. You don't need to delete them. How do you add ×××? Ignore it, delete it. (net user ××× /del), turn off unused shares. (net share C$ /del, ...).

5, input method vulnerability

Solution: 1. Delete or rename the vulnerable files.

It is best to delete the three help files WINIME.CHM, WINPY.CHM, WINZM.CHM. Will you delete other?

6, the most important, also very easy to use, generally invincible

Under cmd, enter c:winntsystem32 write command ren net.exe netwei.exe (back car). Ok, in the future, even if someone else enters your computer, you can't use net user username pass /add to add users, and you can't use net localgroup administrators username /add to join administrators, huh, huh! This command is used to create users and improve administrators. It is. Change to netwei user.

7, the last step, but also the key, this can prevent formatting!

Write commands in CMD: C:>DOSKEY FORMAT=Bad command or file name! ( Enter) This is the lock command. You can also lock the DEL. When someone else maliciously formats your hard drive, the system will display: “Bad command or file name!” and refuse to execute the format command. If in some special case, you need to format the hard disk yourself, what should you do? You can enter the following command:

C:>DOSKEY FORMAT= (Enter) so you can It can be formatted as before.

Basically, the security of the computer is usually done well. If you can follow the 7 rules in the tutorial, your computer will not have much problem, of course, if you have more Good methods are also possible, I hope to help you.
