Cant understand why so many people hate NAV. I've been using it for the past 4 years on at least 10 computers in my own office, sold it to about 200 customers this year alone and all of them returning customers from the previous years of using norton. They have really upped their game the last three years and I get infected computers on a daily basis that I clean up with NAV. My office PC I use to clean infected pc's has removed more than 5000 infections so far and is still running in perfect condition.
It is usually bundled free with new notebooks and it is the 1st thing that is uninstalled after boot. I have not seen their latest offerings but could not tolerate their constant in-your-face interface and notifications etc...notify, request user action, prompt, confirm prompt, launch NAV, prompt, request confirmation, confirm - aaaaargggh. It also tended to just soak up resources... slow the machine down and just kind of invade the operating system.
And then... just when I thought it could not get any worse, NAV would just throw a wobbly and some arb error code that required some sort of remedy from Symantec after a Live Update that, if lucky, only ended in a BSOD.
NAV = NO WAY, NEVER AGAIN. EVER.
Switched to NOD... small footprint, effective, never failed at all.
Now using MSE and it too is light on resources, effective, unobtrusive, and free!
