URL Mal Alert while running a Game

Hi All

Windows 10 x64 16299.98 Fall Creators 1709 --clean installed when it came out
8gb of ram
Intel I7 Processor
Avast 17.8.2318

Issue is was driving in the game, and all of a sudden got an alert for URL mal detection, not once, but several times, finally decided to clear browser cache,and it finally stopped, but why was it saying slplugin.exe when the game is suppose to be excluded per the directions from the Game Developer Firestormviewer.org
