Good news for anyone who hates Vista’s exceedingly annoying UAC prompts: Symantec has said it will develop a Vista add-in that delivers UAC-level security without UAC-level annoyances.

Rowan Trollope, vice president of consumer products at Symantec, told CNet what everyone who’s ever run Vista already knows — UAC is a major league headache, and enough of one that many people will simply turn it off.

“I have been running Vista for a while, and UAC bugged the heck out of me–to the point where I tuned it out and, eventually, turned it off,” he said. He recognized that doing so made his PC less secure, though. So Symantec is working on some way to improve on UAC so it is less intrusive.

No details yet from the company on how it plans to do that. But anything it can do will be much appreciated. I’m on the verge of turning off UAC as well, but haven’t because I know it increases security. And I’m not alone.

The move is important for Symantec, because like other security vendors, it faces a potentially uncertain future. Given that Vista includes a good firewall, free anti-spyware in Windows Defender, and plenty of new security under the hood, it’s going to be tough for Symantec to keep selling a lot of security products. Making it more difficult is that Microsoft sells OneCare, a security solution that includes an anti-virus piece as well.

So fixing UAC will not only be good for users, but it could be good for Symantec’s bottom line as well. It’s an instance where we all might win.
