ciao pidue, da cosa si capisce che si tratta del link optimizer, cosa bisogna guardare?

sei un grande, ma lo sapevo gia. alla prossima.

Allora, dopo tutta la procedura che mi hai descritto questo è il log di Hijack. Il semaforino è scomparso ma uno dei programmini che ho installato mi avverte che una applicazione tenta di connettersi : C.\windows\sistem32\microsoft\serv\service.exe. Ho provato a cercare il file ma nelle varie cartelle non l'ho trovato, o forse non me lo lascia vedere.
Tu che pensi?

Ciao, fai questi controlli:
Start >> esegui, incolla la stringa control userpasswords2, ok, verifica se c'è un'utenza con nome random. Se la trovi, eliminala.
Se c'è l'uenza parassita, c'è un servizio associato. Sempre da Start >> Esegui, incolla la stringa : services.msc, vedi se c'è un servizio che ha lo stesso nome dell'utente random. Tu fai intanto questi controlli, poi:

in modalità provvisoria, lancja HijackThis
rendi visibili le cartelle nascoste ------ > procedura:
da Risorse del computer:
Strumenti >> Opzioni cartella >> visualizzazione;
metti la spunta su:
Visualizza file e cartelle nascoste;
togli la spunta da:
Nascondi file protetti del sistema(consigliato)
e fixa le seguenti righe:
______________________________________________________________________________________
O2 - BHO: Class - {8024FF3D-9A7F-0CB9-0C5D-532A996DAE20} - C:\WINDOWS\dqljl1.dll (file missing)

O20 - AppInit_DLLs: \?C:WINDOWScom1.sxi
______________________________________________________________________________________

Fixa tutte le righe 01

Se riesci, camcella il file in rosso:
C:\WINDOWS\system32\Microsoft\serv\service.exe

Può darsi che tu non riesca a cancellare il BHO, è tipico del virus.
Start >> Esegui. Incolla la stringa %temp% e svuota la cartella temp.Accertati di vuotarla, perchè alcuni virus sono lì dentro.

Poi fai questi ulteriori controlli:
vai neelle seguenti cartelle e nota se ci sono files scritti in verde, sono eseguibili (.exe) con nome casuale che XP colora di verde in quanto crittografati :
C:\programmi;
C:\programmi\file comuni;
C:\programmi\file comuni\system;
C:\programmi\file comuni\services;
C:\programmi\file comuni\microsoft shared .

Riposta un log aggiornato.

Allora ragazzi, spero di non aver parlato troppo presto ma finalmente non vedo più questo tentativo di connessione di service.exe, che non so perché, non riuscivo a vedere nella cartella serv, che sembrava vuota. Tuttavia proprio ora nel log vedo C:\WINDOWS\system32\services.exe....non so che pensare

questo è l'ultimo log

per pidue: nella cartella C.\programmi\file comuni\system ho in effetti trovato due file scritti in verde: RFB e LPA (che faceva riferimento a MSDOS)....io li ho spostati nel cestino...che faccio li ripristino?

provo a vedere ancora come vanno le cose e poi vi dico, per il momento tutto bene

ciao

Ciao il log è pulito. Penso proprio che ce l'hai fatta. Sei stato fortunato ma anche bravo, perchè altri, con il LinkOptimizer hanno dovuto formattare. Ti consiglio di attivare gli aggiornamenti automatici, perchè qual virus si instaura in sistemi mancanti di particolari aggiornamenti.
