I use Norton for seven years. The problems with the (upgrade) installation, as I (especially 2006) knew from previous years, are the 2010 upgrade over. No lengthy remove the old version with subsequent reboots and error messages and instructions on the Symantec Web site for assistance in case of problems and ... and ... and more - now: simply, rapidly and quickly walked with me vonstatten the change to 2010 version , CD in and off. After a few minutes the update was completed successfully. The 3-seat version could be installed easily under both XP and Vista. With Spybot - Search & Destroy, long a problem and annoyance because NS therefore could not cope, there are now no more compatibility issues. Both programs run the full satisfaction of my PCs.
The user interface is also clear and understandable. And with the personal account of the installation key is securely stored and retrieved at any time on demand via the email address again. Short - the 2010 Up-Grade version is a product that I can recommend without reservation.
A Kritkpunkt despite everything: Shortly before the end of the subscription period reminds NS constantly - and annoying - in this circumstance. Unfortunately, you can then only a) the subscription immediately (online or renew with CD), or then b) to "Remind me later" to avoid the constant messages. As a genuine respect for the autonomy and customer -mündigkeit Symantec would have here a field c) "not remember" provide.
