Help! file temporanei sospetti

[gahan]

Ciao a tutti,
ultimamente quando arrivo a fine giornata e faccio una pulizia con CCleaner mi trova moltissimi Mb di file temporanei con questi nomi:
C:\Documents and Settings\________\Impostazioni locali\Temp\BIT53D.tmp 19,4MB
C:\Documents and Settings\________\Impostazioni locali\Temp\BIT9D5.tmp 19,4MB
C:\Documents and Settings\________\Impostazioni locali\Temp\BITFE9.tmp 19,4MB
Qualcuno sa di cosa si tratta?
Io ho la netta impressione che si tratti di qualche spyware o virus.
Ringrazio anticipatamente chiunque vorra rispondermi,grazie

Ciao, elimina i file temporanei con programmi ad hoc tipo ATF cleaner o CCleaner che trovi anche nel forum.
Inoltre elimina questo file o cartella manualmente:
C:\WINDOWS\system32\i

Ti ringrazio per la tua risposta,solo un'altra domanda se posso;
è normale che quei file temporanei anche se cancellati con CCleaner dopo solo pochi minuti si rigenerano?
grazie ancora.
