Impossible to install Avast !
« on: January 17, 2008, 03:35:05 PM »
Hello,

At first, sorry for my poor english !
 
I use Windows XP SP2 
 
My PC: AMD Athlon 64 in 2.1 GHz, 2Go of ram, 
 
Connection Internet pare-feu XP 
 
I downloaded setupfre.exe (18.559Kb) 
 
When I want to install Avast4, the software creates a file   
 
C:\Program Files\Alwil Software\Avast4   
 
in which it installs the files then wonders if I want to do a scan 
 
of my hard disks after re-starting, I answer YES. 
 
On one page 'related' DOS, the scan takes place and at the end the continuous boot. 
 
Under Windows, I don't get the icon in the taskbar! 
 
When I open the file C:\Program Files\Alwil Software\Avast4, 
 
the ashServ.exe files, aswUpdSv.exe, ashMaiSv.exe, 
 
and ashWebSv.exe disappears instantaneously as if something   
 
of 'maliciously' came to erase them!!! 
 
Conclusion: I cannot use Avast and it is well a pity. 
 
Do you have an idea of the reason of my problem? 
 
I didn't find any answers on the forums)   
 
Thank you by advance to answer me. 
 
Greetings.

Pierre (from France).

There is a similar topic http://forum.avast.com/index.php?topic=25822.0
Use this tool to scan your PC - http://www.f-secure.com/blacklight

You probably still have an infection, probably a rootkit on your system that is killing avast.

See http://forum.avast.com/index.php?topic=26554.0
http://forum.avast.com/index.php?topic=25941.0

After running the above rootkit tools if nothing is found try these.
If you haven't already got this software (freeware), download, install, update and run it, preferably in safe mode.
AVG anti-spyware or SUPERantispyware or Spyware Terminator.

Do you have any other antivirus in this computer?
