I, too, see that MBAM blocked (Type: incoming, Port: 21320, Process: sdfssvc.exe). Looking at: Program Files (x86) / Spybot -Search & Destroy / SDFSSvc.exe; directly below there is "SDFSSvc.exe.log." In my machine, this .txt file contains three lines which are as follows: 14-04-13 20:33:09 TFileScanHTTPDaemon Successfully started listening on port 21323. 14-04-13 20:33:09 TFileScanHTTPDaemon Successfully started listening on port 21323. 14-04-13 21:35:31 TFileScanHTTPDaemon Successfully started listening on port 21323. What was it listening for? MBAM blocked the incoming, so it never 'heard' anything. Should I tell MBAM to make an exception? Would really appreciate some advice on this issue. Thanks!!! JustDiana-80
