Hello. I am having an issue that started a few weeks ago and I've just gotten around to attempting to fix it. I have a very simple network, all machines are windows 8.1, all connected via gigabit and I use 1 machine to host files and the others to access them. My issue is I use MS Office 365 and when opening and saving files on the network, there is a 5 to 10 second delay. Upon opening, you see at the bottom of excel or word that the file is 'downloading'. I looked up a ton of fixes for this and tried them, none worked. Then I tried disabling KIS on the 'server' and that fixed the problem. Obviously I do not want to be running without anti virus, so I am trying to find out how I can correct this issue. I'm convinced there was some kind of update to KIS about 3 or 4 weeks ago that caused this, as this network has been running for over a year with no issues like this, and no hardware or software has changed. The server also has 2 SSD drives, and when checking network speeds, there is no slowdown outside of office.
Does anyone have some suggestions on some adjustments I can make to KIS on the server to fix this problem? Thank you.
