I'm still experimenting, but you can have Norton's A/V-autoprotect on and still use BSPlayer. Only exclude BSPlayer from files checked by Norton A/V. How?
In Norton A/V's Options window:
doubleclick on autoprotect (top-left below "System") to open further options.
You will then see "Bloodhound"/"Advanced"/"Exceptions"/ ....
(Note translated from Dutch so labels may be named differently)
Click on "Exceptions" then click on button [New] (at the right)
"Browse" to bsplayer.exe
(Check that (only) box (Exclude from:) [x] "Virusdetection"
is checked/selected)
Click [OK]
BSPlayer.exe is now selected as "excluded item"
Click [OK]
(Starting BSPlayer by double-clicking on an associated video-file is OK as well as starting up BSPlayer through its executable (via a link or directly) is OK. So this solution seems OK
for the time being.)
Additional note: this problem also affects earlier versions (e.g. also 0.86 versions) of BSPlayer! (Same
(temporarily) solution!)
(Edited 7 Aug: the box "incl. sub-folders" doesn't need to be selected so I removed it from the text.)
