How to Defrag your Harddisk with Kaspersky installed

Now whats so great about defragging your hard drive?? Nothing. You install any defragging software or use Windows inbuilt defragger and rest is automatic. But the problem with Kaspersky is that with self defence 'ON', it doesont allow defragger to access its files. So the defragger skips kaspersky files and defrag the rest. For some people it may be annoying that even after defragging, the disk is still showing some fragmented files. For them there is one solution:
1. Right click on the system tray icon of Kaspersky and select 'setting;.
2. Click on the option on the left pane.
3. Uncheck 'Enable self defence'.
4. No need to stop kaspersky. You can defrage the hard drive now and after that check "Enable self defence' again. thats it.
