grave problema

[oackley]

Ciao a tutti,
mi è successa una cosa molto strana e credo grave:

ho paura che si tratti di un worm, non riesco piu' a trovare la cartella "C/windows/system32" e non riesco nemmeno ad entrare nel registro di sistema, digitando il comando regedit, mi si apre una finestra nera tipo dos ma non si riesce a fare niente. In piu' nemmeno il task manager si apre...........
xp pro service pack2, kaspersky personal pro, spysubtract 3, e pest patrol non hanno rivelato alcuna anomalia.....

Spero che tu possa postare il report di Hijackthis.

Per regedit , prova a seguire queste istruzioni :

To restore Regedit.exe:
1. Click Start, point to Programs, point to Accessories, and then click Notepad.
2. Copy the following text and paste it into the Notepad window.

REGEDIT4
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableRegistryTools"=dword:00000000

3. Click File, and click Save. Save the file to the Desktop as RegedFix.reg.

4. Exit Notepad.

5. Locate and double-click the RegedFix.reg icon on the desktop to import the changes into the registry.

6. When you are prompted, click Yes, and then click OK.

7. Restart the computer.

Allora, sono riuscito dopo una scansione in modalita' provvisoria con il kav e stinger di mc afee ad eliminare il worm "setup.exe"
Ma devo dive dire grazie a mc afee..............
adesso funziona sia il comando regedit.exe ed il task manager.
ma la cartella C\WINDOWS\SYSTEM32 non si trova!!!!
eppure quando faceva la scansione compariva nei file scansionati...

allego post di hijackthis :

[YMen]

il log è pulitissimo non c'è niente di anomalo o sospetto

[bluepix]

Che c:\windows\system32 sia presente non c'è dubbio.
Il problema è che il virus l'ha dichiarata hidden.

Proporrei questa prova:

start-esegui-cmd (invio)

all'apertura della finestra DOS digitare:

attrib -a -h -r -s c:/windows/sytem32 (invio)


ciao

[oackley]

tutto a posto e ripristinato come prima!
Un grazie a tutti ed in particolare all' amico blupix!
