Avast is not a valid win32 application.

[trance]

Hi.
I did  a restart in my pc and now (for some reason) it say:
Alwin software/Avast4/ashAvast.exe is not a valid Win32 application.

The case is that I can not open the Avast and any other security program like :spyboat or other.

The virus cleaner tool (aswclnr Virus worm cleaner application) work and I did a scan.
The resoltes are:

I can go one an delete this files but I read they do part of windows and may be corrupted and I don't want to go forward because I don't know very well what is this about.

I trough to re-install Avast again.
If is a virus or trojan will be in the pc and dont be recognized, I believe !

On other hand, I delete the suspected files that did this to happen and my pc are running with no problems.... (for now)

Any help ?
I can not be without protection on my PC.
How Urgent is that ??

Thanks in Advance.
