This can be resolved by installing and scanning the computer using Norton 360.

Ty installing the AntiVirus in Safe Mode.

now the norton has released the norton antivirus 2009 and you have to purchase it,if you want to try with the trial version means you can download the trial version from www.norton.com/nav09

go to google.com and input in the search bar: norton removal tool

download and run the tool and then restart and install new version.

1. Yes, uninstall before installing any other antivirus program or security suite. Your computer (and you) will be happier.
2. Once you uninstall the trial version of Norton, go ahead and download One Care. I've heard some good things about it, but haven't used it personally or seen it installed on a client's computer.
3. Symantec/Norton has made improvements to their software uninstalls. If you have a newer version of Norton installed, it should cleanly uninstall from the Add/Remove programs area. If it's older, you may have issues getting it to uninstall - leaving remnants as you mentioned. Symantec has help removing their software completely on their support site if you need help.


Hope this helps! : )
