How to protect ur system from VIRUS

NOTE:You must unhide the system files first.


This How To helps a lot to those pupil who don't want any virus in there computer. This how to deals with protecting your system from virus that enters your computer from Pen drives and other removable drives

You should do following thing to protect your system from VIRUSES-

1. HAve an updated antivirus program i recommend Quick Heal plus 2008 because it actually repairs the file in 90% cases.

2. If u recieve an email attachment from an unknown source delete it

3. If u recieve an email attachment from one of your freind, first confirm from it and before opening read the complete file name of the attachment. Viruses most probably have the extension like these

"school girl.avi.vbs", "hot.jpeg.bat" etc always look at the last extension.

4. When you want to use a pen drive or any usb drive, CD/DVD Drive then as soon as you connect the drive presss SHIFT key it disables AUTORUN. Now scan it from ur antivirus program. If u r not satisfied then do the following

open cmd

type the drive letter of ur usb drive say H: and press enter

now look for the Autorun file if any using DIR command

If there exist AUTORUN file then type AUTORUN.INF and press enter

the autorun file is now opened in notepad

Sample Autorun File[autorun]
open=foo.exe bar
;ShellExecute=index.html
icon=foobar.ico
action=Foo Bar
shell=doubleclick.exe
shell\configure=&Configure...
shell\configure\command=setup.exe
shell\install=&Install...
shell\install\command=setup.exe
Shell\Option1=Text1
Shell\Option1\Command=option1.exe
Shell\Option2=Text2
Shell\Option2\Command=option2.bat
label=My backup data

Observe which program is executing automatically as in the above example

Foo.exe, setup.exe, option1.exe, option2.exe are executing automatically

so to delete them go to cmd prompt

type the drive letter say h:

and then type

attrib autorun.inf -s -a -h -r
del autorun.inf
attrib foo.exe -s -a -h -r
del foo.exe
attrib setup.exe -s -a -h -r
del setup.exe.exe
attrib option1.exe -s -a -h -r
del option1.exe
attrib option2.exe -s -a -h -r
del option2.exe

Now u r safe to open your drive.

Here is another way to customize the autorun option

Variable	Number	Hexadecimal
No autorun at all	181	0xb5
Autorun only CDROMs	149	0x95
Autorun only flash drives	177	0xb1
Autorun both CDROMs and flashdrives (the default)	145	0x91

5. If you have created setting in your email to view the emails without opening it that is on clicking one of the email its preview is enabled then also

disable it, because it also harms ur computer.
