Hi There, We are a 50 user based company with all users on Windows XP SP3 & ESET Smartsecurity 4.0.474.0 Throughout the company users are experiencing Windows explorer crashes when doing the following: Open Windows explorer (either by pressing Windows key and E or opening My Computer and clicking the 'Folders' button. Once here expand one of the network drives and select a folder from the left hand pane. Now click 'Edit', and the error seems to happen about 60-70% of the time. It is the generic 'Windows Explorer has encountered a problem and needs to close' error but occurs on all machines. I have tried this on our domain and on standalone machines with no other applications other than ESET installed. As soon as I install smartsecurity the error occurs, when it is taken off the systems are fine. I have tried installing with the default config and our own and get the error on both occasions. This also occurs on ALL versions of ESET smartsecurity from 4.0.437 to 4.0474. Can anyone help here? ESET moderator - this is quite serious if a bug.
