I can't load avast! after installation

[Figaro]

I uninstalled my previous antivirus software and installed avast! home edition. After reboot my pc my avast! icon on the desktop is not what it supposed to be. When i double click on the icon. The pc shows unable to locate "ashAvast.exe".
I can't locate this application either.
What should i do?

What was your previous AV ?
Do you have any other security based software, e.g. AdAware, Spybot, WinPatrol, PrevX, etc. that may monitor and block new start-up entries ?

The pc shows unable to locate "ashAvast.exe".

Your installation is obviously corrupted...
You need to uninstall, boot, install again and boot.
That files should be here: C:\Program Files\Alwil Software\Avast4\

I tried uninstalling and reinstall again but it is still the same. I tried install other free antivirus pragram, avg, it is still the same problem. The main lauch application cannot be created.
I think some other program in my pc is blocking it. I have ad-aware and spybot on my pc. I uninstalled both and reinstall
avast.... The problem still exist. 
My previous AV was pccillin. Uninstalled it already.

What makes me think again it's not an avast trouble but old antivirus installations that left trash behind in files and Windows Registry  :'(
A removal tool for Norton is SymNRT.
But as you say you just have PcCillin, maybe you can find in their homepage/forum any further help

Well... you need really get rid of Norton.
1) Remove NAV through Add/Remove programs from Control Panel. Boot.
2) Use Symantec removal tool (browse their site to get it, there are one for each antivirus series). Removing your Norton program using SymNRT.
3) Boot.
4) Install avast! Boot.
5) See what you get.

Can you please add the following lines to setup.ini (in avast4\setup):

[BufferLog]
Enable=1

Then start update/repair again, and SetupDbg.log should be generated.
Please, post the contents here, it should give us a clue of the problem.

Other option is posting the last lines of the setup.log (at that same folder).
