I`ve been tempted to go without, especially as I take frequent backups.

Fantastic so when you do get an infected file, you make a back up of it??

I have NOD32 deployed across 8,000 workstations and no problems here.

No, I can roll back to a previous backup. Only ever had one virus and that was caught through the LAN at the Company I was working at about 8 years ago - the company was the first to get hit by it and because it was a new virus Norton didn`t detect it.
I don`t download dodgy tulip.

How do you know it's infected if you have no AV?
By the time you know you have an infection, the infected files could be the only ones left in your backup set........
