Can anyone help me to solve the issue described on next issue? I posted it on
04/30/2008 and it seemed no one saw it (only my post)

I am trying to avoid reinstalling the Win XP.
Professional OS?
Was this post helpful to you?


I wonder if you have encountered something similar:

The real time analizer detected and deleted eight occurrences of a virus
identified as W32/Autorun.worm.bx, affecting the following the registry ( I
think).
The log file mentioned the elimitation of W32/Autorun.worm.bx virus from
NT AUTHORITY\SYSTEM C:\WINDOWS\System32\svchost.ex
HKEY_USERS\S-1-5-21-4119159155-3476068661-3289729497-1154\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
(Hidden, SuperHidden and ShowSuperHidden D-WORD values)

After that, I can not open de contents of a disk when I double clcik its
Icon directly,
showing a panel instead, with a list of available applications to associate
with. Of course I can look explore.exe and open the Icon with it , but it
can not retain the association because the square to select always to open
the disk wthe chosen program, is disabled.

See http://www.google.fr/search?num=100&q=W32/Autorun.worm.bx

and look for amvo.exe

This infection make an autorun.inf on your disks and USB Keys.
And also make impossible to be able to see all the folders...

To access into your disk, a workaround is WIN+E (to open Explorer),
then clic the disk in the left panel of Explorer, the default action is
the Develop (i guess) instead of Open (check with a right clic).

Check
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL
DefaultValue=0 bad
DefaultValue=2 good

Make visible all the folders (hiden and system).
Rename autorun.inf you can now see on the disks.

I made explanations of the mechanism, but, sorry, this is in french,
hope not difficult to understand :
