Fool ur friend using fake virus

Open notepad and type this:

lol=msgbox ("Warning a virus has
been detected on your PC. Press
YES to format your hard disk now
or press NO to format your hard
disk after system
reboot",20,"Warning")

Then save it as Virus.VBS
and go to the folder that contains
it and open it if a window pops
out saying a virus has been
detected it's working. Press yes or
no to close the window and put it
in the startup folder of the victim's
account.
On startup the window should
appear.

Note: This does not harm your
computer as it does not contain
virus.
The Yes and no button does not do
anything except closing the
window. And you can edit the virus
in the sentence: Warning a virus
has detected on your PC to any
kind of virus eg.Trojan Horse like
this lol=msgbox ("Warning a Trojan
horse has been detected on your
PC. Press YES to format your hard
disk now or press NO to format
format your hard disk after system
reboot",20,"Warning")

Oh in between make sure your
victim does not panic and really
reformat his harddisk. hahaha :)
