Computer Hangs While Booting Because of Kaspersky!

May be while installing System Mechanics 6.0 if you does not choose custom installation select what ever package you want to install by default Kaspersky anti virus installs. Because of this your computer gets hangs while you reboot or on next restart.
So how to fix the problem.
Restart your computer and press F8 for menu select (this may be Esc,or Delete or Enter). For me F8 and select the Directory Services from the menu. It will go to your user account may be administrative give the corresponding password. After the computer boots in to user mode select no for safe mode it will popup a system restore. Now you can restore or open control panel and from Add or Remove you can remove Kaspersky and other unnecessary softwares.
Try to minimize the system startup programs open Run by pressing Mod4+R and type msconfig it will open System Configuration tool, remove unnecessary startup programs.
Then you can reboot and run Windows Normally.

Enjoy

One thing Kaspersky is good for anti virus but it slow downs PC. If you want Kaspersky then remove other existing antivirus or try for Kaspersky anti virus which is not included with any other software.
