No programme access in normal mode

[geotan]

Running Windows XP Home SP3 AMD Athlon 64 3200+

Started my computer and found most of the Desktop Icons missing including My Computer.  When I clicked on Start to show all programmes there is nothing there.  Then got a message saying that there was a virus.  Rebooted in Safe Mode and ran CC Cleaner and AdAware.  While I was running these I kept getting a pop-up for an anti virus programme.  This computer is never connected to the Internet but is Networked. 
While in Safe Mode I put short cuts for the missing programmes on to the Desktop but when I rebooted in Normal Mode they were not there.  I tried a system restore but it will not me go back to an earlier date.
Any help would be appreciated.
I aplogise if I have posted this in the wrong place.

I suggest you start by posting the three logs from this guide:

Sorted.  I downloaded and ran MalwareBytes and that solved my problems.
Thank you.
