[WARNING] The file could not be opened!

[crano]

ciao a tutti
ho installato Antivir PE Edition Classic (la versione gratuita) con gli ultimi aggiornamenti.
il report di una scansione mi ha dato il messaggio "[WARNING] The file could not be opened!" su ben 41 file!
non vorrei aver preso un virus o simili.

allego il report di hijackthis:
