How to Disable Autoplay option (which is dangerous for viruses):

As we all know, when we insert a Pendrive autoplay option will appear(it's better if we disable this option)

Steps to disable:

1)Copy the text starting from "REGEDIT4" upto @="@SYS:DoesNotExist" -->

Open a "Notepad" --> Paste it --> Save the file as fix.reg

Note: Don't forget the extension "reg"

Now double-click on fix.reg --> Click on OK.

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\Autorun.inf]

@="@SYS:DoesNotExist"

Note : After following the above instructions, whenever you place any autoplay

CD\DVD all you have to do is go to "My Computer" --> Open the CD\DVD drive

---> You have to double-click on the setup file.

2) Disable the "Autoplay" feature also.

Click on Start --> Run --> type gpedit.msc and click on OK.

Double-click on "Computer Configuration" --> Administrative Templates --->

System. Double-click on "Turn autoplay off" option and select the option

"Enabled" --> Click on OK. Close that window. Now logoff and logon into your

account.
