We order and paid with cr card Norton 360 for 3 computers. After completed the first down load the program could not erase in our computer the previous version of Norton: it entered in a continuous loop displaing this note: "Prevous programs erased, please Restart your computer". This step was automatically repeated 11 times. Finally we proceeded to make a Shut Down. Results: we lost this Norton 360 download and also the previous version of Norton, with no oportunity to repeat the download. In a fully disgust with Norton we proceed to purchase from your rival McKafee but...what hapenned? Norton blocks its downlad. Somebody shall solve this problem. We wath and await.
