ciao a tutti
dopo aver aperto un file pdf si apre una maschera dell'antivirus MSE ha che dice "rilevato sul PC la presenza di file che non riconosce"
in sostanza chiede di inviare due file a microsoft per l'analisi.
il primo file è il pdf che ho scaricato da una e-mail mentre il secondo file è questo
C:\Users\xxxxxx\AppData\Local\Adobe\Acrobat\11.0\Cache\RdLang_PDDom.ita

potete spiegarmi cos'è e controllarmi il log file?
grazie infinite

Ciao.

Si riferisce ad Adobe Acrobat e sembra legittimo.

Di questo, non avendo nessuna notizia, non ti sò dire.

Il log di HJT non presenta infezioni.
