Hi ARTY DAN I would try NOD32 home edition, it gets good reviews. It does not hog your system, you don't even know it's there working in the background. I got my from click here they did have a good deal on 2 years subscription for £33.18 + vat. You have it on trial, and if you don't like it, there is nothing lost. Hope this helps. Regards sconedd.
