I ran norton years ago then stopped using it when it became bloated. after reading reviews and wanting to try the pulse updates i decided to try it again after about five years. i’m having major problems with updating. i have it on two computers on a wired pna network. on one machine it works very well and i’m happy with it. on the other machine on the same network using the same router i have problems. it will update when i boot it up, but after that it’s very erratic. it will go for hours without doing a pulse update. if i click on live update it usually does nothing. both machines are about the same. the one it works on has an amd 64x2duel core 4400 processor with 2gb ram. the one it doesn’t work on has an amd due core 4500 processor with 3 gb ram. the hard drives are synced, so they are about the same. i’ve uninstalled and reinstalled, i uninstalled it again and used the norton removal tool and downloaded the latest version form norton. i applied all of the patches on the norton web site, i’ve installed the dns correction tool. i’ve run a virus scan. i haven’t had a virus in years. i put the router in dmz mode. i put execeptions in the windows firewall for norton. i finally called support and they spent about three hours doing the same thing over and reinstalling everything again. they finally said they didn’t know what the problem was. i was running avira on both machines previous to this and they updated fine. is there anything else i could do before i give up.
