Does Norton anti-virus slow down a computer?  Seems to have done so on mine?

every program does. Especially when the program takes up a large percentage of your memory. Add more ram.\n\nOr clean up your startup using msconfig.

Do you have an antispyware? Run a scan because most of them are monitoring tools and thumbnails. Install the tune up utilities and evrything will be just fine. Ya they do slow down your computer as they use up ur RAM and also the booting time is increased.

the best thing to do is firstly,- uninstall Norton then take the driver disk and place it under your coffee mug, then cut your losses and go buy an anti virus program that works. install that one and you will be fine........ a bit of a sarcastic answer i know and apologise but i just can't see how Norton are still going, although saying that- their backup program "ghost" is good but i think they have lost the edge on anti virus detection and the anti virus is very resource hungry...........just my opinion

Well it seems to be a slowdown due to a trojan not checked by your tools.\nSo first of all make a back-up or transfer all  your data to another support. Then format the residential HDD and everything will be fine.\nIF this is too much complicate and time wasting I'll suggest a couple of links where you can connect and get better freeware to clean-up your system....let me know.\nb/regards

I used to run the Norton AV, and I found that it does not find all the bugs that it should.    It can stop a virus as it is trying to come on your computer, but it hardly ever detects Trojans, which is a big problem, and it easily allows hackers to come into your computer and mess around.  or it can simply send all your personal info to a website.  or even worse,  format your system.\n\nI switched over to Mcafee Antivirus...  It has been on my system ever since, and it doesn't take as many resources as Norton does either.

What version of Norton are you using? are you using 2005? If yes, they you dont have to anything. It has an in built Anti spyware, which is heck lot better than Windows Defender. I would not personally recommend it to u coz it will make ur compture pretty much slow. Also, they may have some conflict with each, which may coz hard drive Crash, slow running comps, weird behaviors etc.

I am betting you're using a resource hog as an antivirus program...I'd guess you're using McAfee or Norton. If you are you're never going to speed up your computer until you remove these hogs from your system and install a good anti-virus that does not use up all your computer resources.\n\nI suggest you use AVAST - http://www.avast.com/ it's free and it is very highly rated. But, if you're going to install a new anti-virus - uninstall the one you have now first - otherwise you could damage your operating system and neither anti-virus will work well.

It's possible your pc may be infected with a virus. Trojan virus's tend to crash your computer, change your homepage at random, shut down your pc while you're in the middle of something, and they slow your system down tremendously. I would try scanning for viruses to see if that is the problem. \nI didn't realize that my norton antivirus had expired, so for almost a month, I didn't get any norton updates, and unfortunately ended up with 26 trojan viruses and 3 worms. I did a full system recovery, and installed a free virus protection called AVG. It works very well, and I'M BACK!!! It was a horrible nightmare!

You may not run any applications but there are a lot of things running all the time in the background to keep Windows going. If you have Norton Anti-Virus, it does gobble a lot of memory. And Norton Security even more.\n\nI would also suggest that you increase your RAM to 512.\n\nBesides that, Spyware is the biggest culprit in slowing down computers. Download Spybot and run it. That will take care of any spyware and protect you from future ones.

i dont like nortons but i use panda, it runs all the time which could be a draw back, but it doesn't slow this machine, the older pc it did but then so did xp. It firewalls blocks unknow script intruders and so much more. I have to install less helper programs, so that is good in terms of fewer program conflicts.  here is a site with 2006 reviews on antivirus products maybe that can help.\nhttp://antivirus-software.6starreviews.com/?Refer=Goog&Keyword=antivirusb&gclid=CO3OxI7_2YQCFQHAJAodWHg9cQ

Well norton purposely does that in order for you to upgrade or spend anything towards there product. " Oh, if you upgrade to , ya da ya da, you can get rid of those" this and that so if thats your protection good luck.

You might have a faulty file with your norton anti-virus software. I would try un-installing it and re-installing it again. If that doesn't work, you should try to contact your vendor to see what's up....

Norton AntiVirus is way too big, bloated and intrusive. You can't do anything without it butting in and messing you up. The last time I looked, it was 33.8 MegaBytes and you practiclly need a wheelbarow to haul it around.\n\nI have heard that it will put up a good fight when you try to uninstalled it but, Mcaffe has a tool to help with that.\n\nGood luck!

You really need 3 things, Firewall, Anti spy ware, and antiVirus... AVG anti virus will not slow down your computer. Also Spy Bot search & destroy will keep spy ware at bay! both are Free!
