I've been using Norton, if you can believe it, since it came out, during the DOS 3.1 days. I have NO trouble with it at all. A lot of people seem to, but I exclude the files and folders having to do with Steam, FSX, FS9, and so on.
In all the years I've had it, the biggest problem I think I had with Norton was it messing up my 20Mb Hard-Drive, because it couldn't recognize more than 10Mb. I reformatted, split into 2, 10Mb virtual drives, and the next version came out solved the problem. I was so happy, having such a big HD available! Does that tell you how long ago, and how minor, it was?
Just as a side note, all freeware aside, I use Norton Utilities too. After all, he invented a lot of them, so I figure he knows what's what. I understand Peter sold all his interests in Norton to Symantech (sp?) and retired now. Rich SOB too...
Have fun! FSDT products sure help, no question
