why does norton slow down my computer?I downloaded the version that I received as a Christmas gift which is the 2009 Norton Antivirus with Antispyware and it slows down my computer sooooo much. I hate it. My normal antivirus protection is called Shield Deluxe and I downloaded it off of the internet and it is great! It had very good ratings, some of the best! I absolutely love it b/c it doesn't slow anything down and catches EVERYTHING. I download music alot and this catches it b4 I get the whole song downloaded. I wouldn't recommend Norton!!

You can try temporarily disabling Norton AntiVirus whenever you need the speed and/or processing power (e.g. video editing, video encoding, gaming, etc). Just make sure it automatically re-enables after x minutes or that you restart your computer.
I'm not sure about newer Norton software, but I remember that it scanned through almost everything (didn't have MSN messenger back then). It was quite extensive and it stretched out the installation time of many software applications. Today, most antivirus software are designed with Heurustic scanning, which detects virus-like behaviour instead. This can help reduce database size.
My best advice though is to get AVG anti-virus, it is free for personal use and it works wonderful!!
I remember I tried to use AVG free antivirus, but I uninstalled it after some time, because it got on my nerves and a little bit I felt that it got slower, even though I could tweak it.. but I don't really need an antivirus, Clam Win free antivirus is okey for me, even though it doesn't do to much and I also use to check for some spyware and trojans using Spybot S&D and I also tried Super Antispyware, which have fixed some problems on my XP earlier where Spybot S&D couldn't find anything..
With most Norton products, you can choose the time that the antivirus programs decides to scan your computer. Usually, it will run a quick scan on startup, and when your computer is idle and not being used.
I've noticed the ccSvcHst.Exe processes occassionally spiking to 96% of the CPU for 20 to 30 minutes in mid afternoon. It makes my system unusable.
Norton support simply sends me the same old "remove temp files, etc." advice and seems to ignore the fact that their process takes over the computer. There is no excuse for a product like Norton to ever completley take over the CPU. If it takes a while to scan something, have the decency to allow other processes to make progress as well.
I've used Norton for years. I dropped McAfee back when our company was infected because McAfee missed a virus that Norton caught.
Looks like paying for commercial software only gets you poor service that makes no real attempt to resolve your problem. Norton makes me ashamed to say I'm involved with the computer software and security business.-reply by Mike Jordan
Norton 2009 just installed 3 days ago. My computer is virus-free - installed Norton on advice from a friend. My computer is totally unusable. Slow? Norton has taken over my machine COMPLETELY. What the hell were they thinking when they created this stupid product? It is a freaking nightmare to install and now this? No support at all - well, actually it is worse than no support - they have BAD support from people who had me uninstalling dot net framework versions just so I could get this product to install. Unbelievable. I have been swindled and I will never buy another Symantec product again. Does anybody have any software for anti-vius that can be truly recommended?-reply by Dave
Yep, I just installed a new copy of Norton and now my internet browsing is so slow I might just remove this cursed program completely. I can't believe how it affects my browsing. My previous version of Norton was trouble free...-reply by Adrian
It practically locks you out of your own computer. I have but one account and that one account is the sole administrator account. I cant save changes in msconfig, I cant micromanage system processes and I am now locked out to older 'my documents' subfolders. I'm getting, "Must be and administrator or have admin access".
Flexibility? Optimization? Forget about it. No matter how you tweak it, the core norton processes dominate your task manager, peaking at the high 80-90s cpu usaged irrespective of CPU speed, strength or max RAM capacities, while supposedly 'disabled' for 30 minutes. In the event your web browsing and programs are rendered totally unusuable.. Guess what? Good ol Norton saw it fit to make their product and their processes tamper proof.
Forget the days of Ctrl+Alt+Del to close out that old resource hog in task manager, with this product, you forfeit control, micromanagement and distribution of system resources on every level.
Shall we get on the subject of cpu heavy programs, online games and applications? Take World of Warcraft for example... As a poster stated before, you don't want to be in a situation where you make a full of yourself because you drop to 1fps in a raid.
With this program, you WILL drop to 1fps on a raid pull and make a fool of yourself.. And consequently piss of alot of E-Friends.
Do you get security? YES, at the price of a completely unusable computer that has 'securely' locked you out of it!
Just look up the statistics for the Norton Antivirus I/O File delay. It is recording breaking.
I already used Kaspersky 2010, Avast 5.X, Norton 2005, Norton 2006, Norton 2009, and Norton 2010. When Kaspersky is scanning, your computer slows down ALOT. Avast doesn't do anything. It doesn't scan automatically, and gives me alot of false positives.
Early Norton versions (2005 - 2009) also slow down your PC extremely hard. This issue is COMPLETELY fixed in 2010. I'm a happy customer :)
There is only 1 thing. If 'SONAR' detects suspicious behavior, it just deletes the file, without asking me. That's really annoying, because most of the time it's a game or something (it picks up keystrokes...) I only know, that it's a great antivirus solution, wich DOESN'T slow you PC down.
I have Norton Internet Security 2009 and it has made time in front of my computer miserable. I run a business and the problems I have had with slow booting up and downloads in addition to stopping sending and receiving of emails has been horribly frustrating. Changing settings does not help. The email problems come and go and have caused me to lose valuable time. Norton support refuses to acknowledge any problems. Now I am trying to figure out what anti-virus program to use. There is no consensus out there.

well I have the norton 90 day trial and thats actually better than the real thing cause I had to uninstall it to add a game on because when it was almost down installing norton would close it and I had to start over like 8 to 15 times before uninstalling it, but after I downloaded the trial it works pretty good, and my laptop's not gettin slowed down at all, but yea I agree it sucks, on my desktop I have somethin called CA which is PERFECT! it performs automatic scans like every day on its own and it scans everything, and if it finds any virus or somethin it'll delete them after you choose to, just in case the "virus" or whatever isnt rlly a virus. And its like 0 a year.-reply by Evil Lizard Master
