I already took it out a bit back and put microsoft security in, long story I did have macafee free from BT first and was not pleased with it, so i put the norton in and it sent my computer into a world of it's own, like I said I think it was too strong a version.................dunno up till then I had always used norton on each computer I have had. going for a lie down now as I am crippled through sitting here all day doing scan after scan
