Thanks,

I’ll add my own experience to your post.

Before starting, I unpluged my internet access cable.

First, I zero-sized 3 files (buritos.exe braviax.exe and karina.dat) in both C:\WINDOWS\ and C:\WINDOWS\system32\ folders.
I also made them hidden and system files…

Then I restarted the computer, so that the evil hidden process is not running anymore (karina.dat).
From this time, Windows will complain many times about karina.dat, then simply click OK.

You can now repair the registry, the process won’t bother you anymore.
Go to the following registry key : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\windows
and replace appinit_dlls=C:\WINDOWS\system32\karina.dat
by appinit_dlls=C:\WINDOWS\system32\karina.da
(or anything else that makes windows not finding the file)
press the F5 key to check that the value hasn’t been set back to it’s previous value (if so, restart operation from the beginning)

Now you can safely repair the beep.sys file.
Get a safe version from the installation CD or from a friend (should be about 5kb) and put it in the 2 following folders (erasing previous file) :
C:\WINDOWS\system32\dllcache
C:\WINDOWS\system32\drivers

Now the virus should be gone, and not coming back by itself.
You must now install an efficient anti-virus in order not to get infected again when you will access internet.

FYI, I also disabled the 3 services below, but I am not sure they are viruses, and if so, they are most probably not related to braviax :
1) Gestionnaire de session d’aide sur le Bureau A?A? distance – C:\WINDOWS\system32\sessmgr.exe
2) QoS RSVP – C:\WINDOWS\System32\rsvp.exe
3) Windows Server IP Verification Service – C:\WINDOWS\system32\wsivs.exe

Good luck !!
