I've used Norton for years and have been very satisfied.I purchased a new Systemworks 2006 premium 12-5-05 and din't get around to install it until 12-9-05.I was about halfway through the installation when it hit and error with vague instruction how to use the patch.After exhausting my knowledge I called in a PC tech and it took him over 30 minute to finish loading the disc.Ran the scan live update and all the other necesary garbage and i thought I had a good system,but on 12-12 -05 I went to open one of my drives and it was locked up solid.I called the tech again and after trying all option he went to safe mode and downloaded all files off of that drive onto another drive(I also found before the tech came in that it had locked other web pages even the dictionary)Still in safe mode we uninstalled the Norton disc and all drives and web pages were operatable.I have no idea what is in this disc but if any one else purchases this unit be prepared to experience some problems.There is no doubt in my mind that all the packages will have the same problem.Louie Roy
