Hello, Very recently, my system started freezing when I double click mp3 files, and Winamp would not open. In Vista, I get a "Remote procedure call failed" error after the freeze, while in XP, the screen simply freezes and I get no error message. I double click again, and Winamp opens. I close Winamp, and double click the file, and again the freeze/error happens. So in summary, the freeze/error happens only every other time I open mp3 files. When I turn off NOD32, this behavior goes away. I have reproduced this problem on two systems. I am using latest NOD32 and latest Winamp. This only started happening within the past few days, so perhaps one of the updates includes a false positive, so NOD32 prevents Winamp from opening. Thanks.
