Symantec/Norton was expcised from my personal machines some time ago. I never used Norton Internet Security. Just the way anti-virus alone infests the PC was bad enough. Unfortunately, my work PC runs Norton because corporate requires it. But it is their PC.

I also see where Symantec is developing a replacement for Vista's UAC. I shudder to think what that would do.

>I just had yet another instance of a Symantec/Norton antivirus product (in this case, Norton Internet Security) causing major problems with a client. She lives in Outlook 2007 on Vista:
>
>- she lost the Reading (Preview) Pane completely
>- when we turned it back on, it was empty and would not display the currently selected message
>- all incoming and outgoing mail was stuck/hung
>
>Multiple Outlook restarts, Office Diagnostics, and complete machine restarts had no effect. PST file size was "relatively" small, only 550MB.
>
>Uninstalling NIS and running the Norton Removal Tool fixed all problems immediately.
>
>So, as a reward for explicitly buying NIS and getting Best Buy to put it on her new computer a few months ago:
>
>- she lost almost 4 hours of her time
>- she has to pay for 45 minutes of my time to figure out what the problem was
>
>She's now using AVG Antivirus (the paid version at http://www.avg.com/home-and-office-security). The "Plus Firewall" version is not necessary on machines running XP SP2 or later, which already have an adequate firewall. I have a number of clients running this product, with excellent success.

>For small office networks, I've had good success with the Trend Micro suites.

>Symantec/Norton antivirus products continue to receive my maximum de-recommendation/condemnation. Fundamentally, you pay good money for a protection suite in order to make your life easier. Symantec's products fail miserably.

>I haven't had any recent experience with McAfee, but a couple of years ago I set up some brand new Dell laptops with McAfee trialware preinstalled. Trying to uninstall that crapware BSODed all the machines; I later found out from Dell tech support that that product could only be uninstalled via a safe mode start. That's the angriest I can ever recall being about a piece of software, and at the time I swore I'd never consider McAfee again.
