What is the difference between Norton AntiVirus 2004 and Norton AntiVirus 2010 ?
Not much. Every second new viruses are created. To combat these,
anti-virus software designers think of new ways to defend computers from
these viruses but no one anti-virus can be 100% safe.
To combat new viruses, anti-virus programs download new 'definitions' or schemes to protect from new viruses.
If you like a direct comparison of the two versions, read below:
AV
2004 was designed for XP and older OSes. As of 2010 we have Win Vista
and 7 with new kernel and user interface. To keep up with new changes,
AV providers upgrade their software so that it will work flawlessly.
In
simple words AV 2004 works similar to AV 2010 BUT for older Windows. AV
2010 should work with older Windows but it is primarily designed for
7's revamped UI and kernel.
If you had a chance to work on Win 98
and migrated steadily to Win 7 you would notice that older programs
that ran on 98 look really outdated and 'boring' compared to new
programs designed for 7.
Also note that companies stop providing
support for old programs after some time they release the new product.
One of their objectives is to encourage people to spend again or attract
new customers which in turn will increase their revenue.
If you
are using XP and AV 2004 you should not find it necessary to spend cash
again unless Norton requires you to upgrade or they stop providing
updates.
If you are a new customer and use Win 7, AV 2010 is a good idea. Before making a purchase, keep in mind that free options are also available for home users like AVG free (free.avg.com). I find it is quite satisfactory for an average user and I am using it past 5 years with little to no issues.
