I have to say my experience so far has also been one of 360 just doing it's thing, unobtrusively, in the background. No apparent change from running 360 v5.

Well it has been some time since I have had any Norton security product on any of my PC's, mainly because of there reputation (rightly or wrongly) for slowing the system down.

However whether it's because of faster systems or Norton getting better, or as I suspect a combination of the two I am really impressed, no noticable slowdown whatsoever just does it's job in the backround!

As a first time user of ANY Norton product, I have not had any problems, so far, although yesterday, while on PCA, the refresh rate of pages was extremely slow. On my other computer at the same time, the PCA site was OK.This problem went away after a shutdown and restart.

Also during install I was asked to remove Zonealarm and System Mechanic - which I did do.(using another uninstaller, REVO).

I reinstalled System Mechanic today and so far, everything is working ok.

There is no obvious performance differences between 360 and NIS 2011 that I used previously. That is a good thing and I am very pleased that nothing much has changed. I do however have a couple of issues after using it for a few days:

1) I tried to install Serif WebPlus 3 starter edition from the PCA cover disk Jan 2012. Norton flagged a file pb7de1.exe as behaving suspiciously and removed the program without prompting from me. I tried again on a machine running NIS 2011 and it did the same. What I do not know if this is an issue with Norton, PCA cover disk or Serif.

2) I now have a small Norton gadget in the top right hand corner. When hovering over that it brings up another small box to close the gadget or drag it. The latter is greyed out and I cannot find a way to activate it - not that I want to.

The first issue bothers me, the second does not.
