Hi,
Thank you so much for all your advice, I install Norton 360 6 months ago, but my PC went really slow over a period, so some one suggested to get rid and install Avast! which I did, since the Trojan episode earlier, a friend uninstalled Avast also and put on AVG this evening, so, I didn't realise I still had anything to do with Norton left on my PC, am I better sticking with the AVG programme? which is what the friend put on this evening, he works in IT, but gone home now, and Im absolutely useless with technology, Im sorry to be a nuisance.
PS Do I need to check any of these items off in the window "Trend micro" thats open before I delete or do anything with it?
