I spent 6 hours and two service calls w/ Symantec trying to get this software to install. I have no idea how well the software works, because I cannot get it to install. To install the software all previous versions of Norton must be removed from your computer. I followed the instructions in the manual, but the software continued to detect software that needed to be removed. It does not tell you what software or where on you hard drive it's located. So, I followed all of the instructions on Symantec's web site. Still the installer detects previous versions. Both service calls directed me to follow the web site instructions. Already done!!!How is a utility that is supposed to improve PC performance so hard to install? If it can't fix these problems to install itself how is it going to fix ANYTHING on my PC? Anyway, I am goint to try and return it.
