No, don’t delete File IO Surrogate while Vegas is running, its part of it’s

Norton is a death trap, you shouldn’t even have it installed on your editing

And the fact that things start behaving oddly since you update it, is a clear
sign and deactivating it alone wont help.
There are other far less intrusive and resource hogging Antivirus out there.
