Do not use Norton security period. It's a massive drain on resources, false flags everything and is a complete rip off.
I use a combination of Windows Defender and common sense whilst browsing the internet. Never had any problems
Been using Microsofts built in protection for nearly a decade and funnily enough never had a virus. My dad insists on using Norton and he gets threats everyday, several times a year i have to go and rebuild the windows registry because Norton has deleted a critical system file! I think Norton is in fact the virus.
Last time I checked, Avast does delete the executable after a few runs so you do have to set an exception for the editor folder to keep that from happening. I think it's a good idea to do that anyway for all your heavy DCC apps and games in order to reduce stutters.
