igor, YES, I've entered the file types type as presented here in the (program settings-exclusions-*.mpg,*.mpeg,*.avi,*.wmv,*.wma,*.mp3,*.asf,*.midi,*.pdf,*.wav) . YET,when i run an AV scan (of any kind) i get Avast scanning ALL the file types (INCLUDNG all file types in the exclusions list). Just,how can this thing be avoided,and time can be saved in process of scanning ? Thanks . Z.
