Titolo: Errore explorer.exe ogni 20 secondi!

Salve a tutti,
non riesco a venire a capo di una grave situazione di errore sul mio pc,
equipaggiato con WinXP e service pack 2.
A partire dall'avvio, ogni 20 secondi viene visualizzata la segnalazione di
errore "Si è verificato un errore in Explorer.EXE. L'applicazione verrà
chiusa."
In realtà explorer sembra funzionare bene, e posso continuare a lavorare
ignorando la segnalazione di errore.
Se invece premo il classico "Non inviare", explorer viene chiuso e
riavviato... e dopo 20 secondi esatti si riproduce lo stesso errore.
Decisamente sembra il comportamento di qualcosa di malizioso.
I dettagli dell'errore sono i seguenti:
AppName: explorer.exe AppVer: 6.0.2900.2180 ModName: msvcrt.dll
ModVer: 7.0.2600.2180 Offset: 000360cb
Ho provato a fare uno scan completo della macchina con AVG aggiornato e con
Ad-Aware, ma non rilevano nulla. Insomma non riesco a venirne a capo.
I processi attivi ed altro, li riporto di seguito, loggati con HijackThis...
spero che qualcuno di voi possa aiutarmi a capire di che si tratta.
