My experience with Norton 2009 - Antivirus Slows Down Your PC?

My experience with Norton 2009 Antivirus Slows Down Your PC? 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!! -reply by Amber Keywords:

I think it slows down your computer because it checks everything, every image you are viewing,every text you are reading and pretty much everything you are downloading. That might explain slowing down internet. As for slowing down computer normal work i dunno alot about antiviruses but i believe since Norton has a high database containing viruses and spyware info, maybe since its checking through a big database it takes more processing power. As for your old antivirus/spyware, it might have figured out many viruses, you cant be sure that no viruses were not caught. Just because it has high rating doesn't make it good. Sacrificing speed for security is good. Just turn Norton off when you want to play an offline unaffected game and turn it back on when you are online or when you download a program/game.

Norton is well-known for it's slow speed and it can bog the computer down by quite a bit. When I had Norton AntiVirus 2005, it didn't affect a lot of my normal computing actually.

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 heard a lot about Norton slowing down computers, because it checks lot of things, I never really used it, but I think you can optimize it to make it work faster.. As I know ESET NOD32 is one of the best anti virus softwares which isn't consuming lots of processing time and doesn't really slow down your pc to much, especially if you tweak the options a little bit to fit your needs! And it secures your computer from most bad stuff..

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..

The latest version of Norton Internet Security, i.e. 2009, runs quite well on my computer, which is running Windows Vista. According to Symantec, it is the most lightweight and less resource utilising version.

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.

Norton 2009
My experience with Norton 2009

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.

Norton Anti-Virus Slows PC Performance
My experience with Norton 2009

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?
