Make frnds scare for VIRUS

Make frnds scare for 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.
