today I downloaded new version

From where did you download avast? From the official site?

Did you try to install the new version over the top of the old one ?

It may be better to do a clean reinstall.

Download the avast! Uninstall Utility, find it here and save it to your HDD.

1. Now uninstall (using add remove programs, if you can't do that start from the next step), reboot.
2. run the avast! Uninstall Utility, reboot.  If step 1 failed it may be necessary to run this from safe mode, once complete reboot into normal mode.
3. install the latest version, reboot.

I did it several times but there is no difference .

To use aswclear I should go in safe mode , but when I want to load XP in safe mode my PC will reboot and doesn`t go in safe mode  :'(

Also some times a black transparent background appears in front of my screen that has one message with this content (Somedeal) : One programme is trying to close your protection module , are you proceed ?
And Has two choices : Yes , NO (with a countdown)

Please help me  :-[

If you can disable the self-defence module (Program Settings, Troubleshooting) you should be able to run the aswclean.exe from normal mode. The black transparent screen could well be the avast self-defence at work.

However, failure to boot into safe mode could be malware related.

Also see:
How to restore Safe Boot.
The malware may have deleted the SafeBoot registry keys.
Here are some options to restore them:

Could you please upload it on another server for me ?

Why can't it be downloaded ?
Clicking on the arrowed link should ask to download, or right click the link and select save as or save file as (depending on your browser).

Or try this one.

AVZ Restore Safe Boot - Download AVZ from here:
http://z-oleg.com/avz4.zip
Unzip the file and place it on your desktop.

Open the avz4 folder and doubleclick avz.exe to start the tool.
On top in the menu[/b], click File, System recovery and select Restore Safeboot Reg keys
Click the "Execute selected Operations" button below.

Close avz.exe.
Delete AVZ4.ZIP, and the AVZ4 folder.
Reboot and Test Safe Mode.

Hi
Didier Stevens sent his registry fix file to me , so my safe mode problem is solved . I used aswclear and uninstalled Avast from safe mode . Then I loaded windows normally and installed latest version of Avast , but again I received same damn message :  :'(  :'(  :'(


I think something there is in my PC that doesn`t let avast to load correctly and also when I did boot-schedule cleaning after installation , Avast didn`t find anything  :(

Check the contents of this file, C:\Program Files\Alwil Software\Avast4\DATA\log\selfdef.log using notepad. This is where the avast self-defence module records infor on stuff trying to access avast files.

I believe this avast warning is the self-defence module at work, so it would be nice if we could find out what is trying to modify ashServ.exe ?

I bet on Bagle/Beagle infection... Can you run a full avast scanning? Maybe at boot time?
If it does not work, maybe you should test on-line scanners (if you need suggestion, just let us know).

There is no selfdef.log in that root , there is only (Setup.txt) in that root .

@Tech
I can only run boot-schedule scan after installation restart . I don`t know how can run scanning from boot manually because I can`t run avast .

Note : After installation Avast , avast icon has Unknown mode :

when I click on it , windows can`t find ashAvast.exe .Also I can`t find it in related folder . maybe this help .

Strange... seems infection...

Just run:
C:\Program Files\ALWIL Software\Avast4\sched.exe /A:"*" /archives

I don't know if that will work as it looks like avast isn't getting to complete the installation, missing files, etc. but it won't hurt to try.

Try these tools to see if there is a hidden infection blocking the installation.
