Problema con scvhost... help!

[allistaire]

Ciao.
Da qualche giorno sul mio pc fisso (con Win7 Ultimate) ho in Gestore Attività una voce di svchost.exe che succhia parecchie risorse.

Dopo scansioni antivirus (Avira free aggiornato), Malwarebytes Anti-Malware e altri tool, ho rimosso una voce di probabile virus (worm/Gamarue.I.165).
Il problema persiste.
Ho fatto un log con Hijacksthis, sottoposto poi su Help2go Detective, che mi ha fatto eliminare due voci (relative a Real e Java).
Dopo i due riavvii consigliati, ho sempre la memoria di svchost.exe che sale continuamente (ora è a 130.000 per esempio e continua a salire).

Ho fatto ancora un giro di Hijackthis e questo è il log attuale:
Potete aiutarmi per favore?
Attendo qualche risposta se possibile!
Grazie a tutti, ciao.

A una prima occhiata, questo non mi sembra un servizio di Windows:

O23 - Service: KMService - Unknown owner - C:\Windows\system32\srvany.exe

Trova il PID del svchost.exe che ciuccia (da task manager/gestione attività), da prompt dei comandi/shell dos usa il comando seguente e poi copia quello che esce, mostrandocelo qui:

tasklist /fi "pid eq tuo_pid" /svc
(al posto di tuo_pid metti il pid trovato)

Mi sembrano tutti servizi legittimi.

Prova questi software che potrebbero togliere le infezioni in modo automatico, aggiornando PRIMA le definizioni (non è richiesto solo per MS safety scanner), facendo la scansione COMPLETA del sistema (almeno il drive/hard disk/partizione di sistema):

• MS Safety Scanner 32 bit (clic) oppure MS Safety Scanner 64 bit (clic)
  (a seconda della versione di Windows che usi)
• sophos virus removal tool free (clic)
• MBAM free (clic)
• superantispyware free (clic)

Io direi di fixare tutte le chiavi con hijackthis, lasciano solo Avira, cosa da fare sempre, tutti quei processi sono solo zavorra, quando serve eseguire qualcosa lo fai da start, fatto questo vediamo se rimane il problema ed eventualmente eliminare anche qualche servizio di troppo. Ricorda che con hijackthis puoi reinserire le chivi eliminate con un semplice click.
