As Randolph mentioned, Symantec Antivirus is currently at version 10.2.
I'm not entirely sure what the objective of your question is? Are you trying to get your boss to put Norton Antivirus 2009 on your work computers, instead of Symantec Corporate? I would advise against this.
Symantec Antivirus (and all the other corporate versions of their product, are truly great products. Norton Antivirus 2009 is quite good, but it simply cannot hold a candle to Symantec 10.2. Having used both products extensively, I was truly impressed with:
The lack of bloat. We installed it on some old Pentium 4's, and it was barely noticable.
The lack of user interference with the product - since all the machines were taking directions from the server, configuring and installing the product was a snap.
Speed of scans - pretty quick, considering the age of the computers.
Instead of going with Norton 2009, I would be inclined to make sure you have the latest version of Symantec Antivirus, next time you renew.
Edit: Based on your comments, I have the following to add:
SAV 10.2 is reasonably recent. I'm willing to bet that the scan engine in 10.2 is comparable to anything you'd find in Norton 2009. This is because consumer products typically move much faster than corporate products.
Consider what really changes in Norton:
- Does it get significantly better at removing Malware? A little.
- Does it get prettier? Yes.
- Does it get some new options / features that may not be required in a business environment? Yes.
In my opinion (having a significant amount of experience in Symantec products) the two are comparable in terms of the technology they would use. Of course, this is just my opinion. Take it with a pinch of salt, I may just be talking out of my rear end here :)
