Desktop Problem!

Hi guys
having weird problem in one of my office laptop, guy having a laptop running 2 antivirus, one expired and the other one NAV was running fine.
I just uninstalled the other one that was expired and restarted the laptop, when it comes to the desktop after rebooting , I can see only the wallpaper and no icons , nothing.

so now I use ctrl+alt+del to logoff from there and then login again and then everything looks fine.

sure one of you guys can tell me where to look around.

Cheers
