- go to c:\windows\system32 folder
- look for these 3 files " defrag.exe , dfrgntfs.exe , dfrgfat.exe "
- now you have to add these 3 files to kaspersky trusted zone (or trusted applications list)
- for example in kaspersky workstation mp4, right click kaspersky tray icon on taskbar > click settings > click protection in top left corner > in the right side click trusted zone button > in the opened window click trusted application tab > click add > click browse > click browse again > now specify all 3 files above one after the other > and make sure to check the all the check boxes (for each file you specify) >after adding files click ok > then apply and ok
Note - another solution is also there, (to disable self defence on kaspersky and run the defragmenter) this one is also worked , but be sure to enable self defence after the deragment complted.
