How can I kill a Norton AntiVirus 2007 install that's slowing a PC to a crawl?

I have used all of the programs so far suggested, and would instead recommend http://www.activevirusshield.com/antivirus/freeav/index.adp. Don't let the name fool you -- this is a free program based on Kaspersky Antivirus (arguably the best commercial antivirus software out there these days) that AOL started giving away a few months ago as a marketing gimmick. It has almost all of the features of the commercial Kaspersky version, and uses Kaspersky virus definitions (which it downloads every few hours). It's a great piece of software, and much more user-friendly than NOD32 or AVG.

http://ask.metafilter.com/mefi/49676#754552, I thought that alert offered a couple of for-pay choices and a new free version. It was a bit early...I'll see it again in three weeks.

AVG has a good track record, wheat, and you sure can't beat the price. Good luck!

caution live frogs: I've had the same experience. The corporate version is unobtrusive and unproblematic. I guess they try to stuff the home version with "features" so people will feel they're getting something for their $40 bucks. taosbat: both of my laptops were running NAV 2003 before I upgraded one of them to 2007. The other is still running 2003, but I'm going to remove it and go with AVG Free on both.

FWIW the corporate version of Symantec AV has never given me any trouble, on older or on newer systems. It doesn't seem to be processor-intensive and is one of the more unobtrusive security products I've used. I have no idea how a product that appears to work this well becomes the craptastic pile of hell it seems to be in the home user version. Two different teams working on it, or what? Seems like a bad decision - if you hate the home version, why would you push for your company to buy the corporate one?

Norton AV 2003 was pretty useful but I think they've downhill since.

I'm running Sygate Personal Firewall (which was free before Norton bought it and http://www.eweek.com/article2/0,1759,1893740,00.asp?kc=EWRSS03129TX1K0000614. You can still get it http://www.tucows.com/start_dl/213160_90233_6648). I also have a hardware firewall on my Linksys router. So I figure AVG + Sygate will keep me covered. I'm amazed that the offer this for free. I'm glad to hear that it works for people. I'm going to uninstall Norton Antivirus from our other laptop (my main laptop). Norton AntiVirus always been a memory and processor hog. And I'm mad at Norton/Symantec for wasting so much of my time with this buggy upgrade.

I've used AVG for several years and got no virus. Last year, both local ISPs started recommending it. I asked both why they started doing that and they said it was because AVG started doing auto-updates for the free version. I had noticed the auto-updates, myself, and had my mom dump Norton Security for AVG and Zone Alarm (and Spybot and AdAware). She gets along just fine with that set-up. When my sister got a new computer this year and had me set it up, first thing: I uninstalled the McAffe suite 'trial' it came with and set her up with the well-seasoned, and more effective, freebies. Today I called both my mom and sis and told them to hit the 'wait 21 days' link. I do remember one AVG major upgrade that went awry...
