I have 1gig ram on my XP PC. I find out today that Internet Secuity requires min of 1.5 gig. This is more the Win 7 or XP.
The PC literally slowed down zero & only a reboot would get the PC back.
Contacted BD 'Chat' which was as much help as a waste of time, they even severed our connection when they could not come up with an answer, except buy more RAM (To run a AV program) What has BD succumbed into.
