Should I renew existing Norton antivirus on my Mac?

When I bought my Powerbook one year ago, the salesman at the Apple Store suggested that I should use Norton Antivirus "just in case." So, I installed it. Now I'm getting notices that it's time to renew, but I've read on this forum that it's probably not necessary to have.
Does anyone have an opinion as to whether I should renew, let it lapse and try to remove NAV and install a free antivirus program, let it lapse and do nothing, or any other suggestions.
Thanks for any help.

Let it lapse, ininstall and get HenWen/Snort combo...

Every bit as good, perhaps better.

Norton Antivirus 12 and Mac OS 10.7.2

I am having trouble with Norton Antivirus 12 on my iMac using Mac OS 10.7.2. When I open the program the Automatic Protection keys are turned off. They
should be on at all times. Can anyone give me some help on this problem?

Norton has a very bad reputation here (thus Barney's response). I have no personal experience with it, but at the same time see no purpose whatsoever in having something like Norton installed. See my Mac Malware Guide for more information. If, after reading that, you still want or need AV software, get a copy of ClamXav.
(Note that my pages contain links to other pages that promote my services, and this should not be taken as an endorsement of my services by Apple.)

Should I concern myself with antivirus programs for Mac and iPhone?

Should I concern myself with antivirus software? I have both Mac desktop, MacBook Pro and iPhone 6+ and since there has been some hacking, I want to make sure everything's safe

From my experience any AV software on Apple equipment stands a much greater chance of causing problems then offer any sort of protection. For this reason, I say that you are best served by avoiding them.
If you are the least bit sensible about where you go on the web and where you get your downloads from, you should be safe. A good site to read about sites to avoid using for downloads is http://www.thesafemac.com/boycott-cnets-download-com/

Symantec Norton Anitivirus 10. for Mac

Recently purchased a new MacBook Pro. Transfered all programs from Powerbook G4 to MacBook Pro on setup. Problem: Norton Antivirus 10 for Mac will not transfer 2 programs correctly: LiveUpdate and Uninstaller. LiveUpdate will not operate and the latest updated version of LiveUpdate from Symnatec will not install or correct the problem (see symantic support downloads). Plus, the Uninstaller provided by Symantec will not recognize symantec programs on you HD. Solution: Removing all Symantec programs for Macintosh by using the RemoveSymantecMacFiles removal utility available from Symantec support. Then re-install Norton Antivirus 10 for Mac from the CD. Then LiveUpdate and Uninstaller will work correctly. Bottom line some programs are corrupted using the setup transfer program from and old mac to a new mac.

I uninstalled Norton AntiVirus. A request to renew keeps popping up everytime I start the computer. Where is this file hidden?

Not needed from the App Store. Go straight to the developer.

Also FindAnyFile, which if you Option click Find will search as root.

For EasyFind, enter the name of the developer or anything else associated with it.

I was surfing the web and got tricked into downloading MacProtector. It says my system is infected!! Of course they want almost $80 to register the copy that is on my laptop. Is this a good product?? Should I get something else, like Norton antivirus?

Yes, turning off Javascript works, but turning it on and off is a pain if one has to make a trip to the preferences.
Why many recommend the NoScript Add-on as one can drag a "allow" button to Firefox's toolbar and turn on scripts on a site per site, case per case basis.
NoScript also protects against other web nasties, like Clear click jacking and zillions of other web based trickery.
http://noscript.net/changelog
Apple Support Forums works fine without Javascript running, I do it all the time, it also supports HTTPS encrpytion too.
It might be that I'm not seeing a lot with Javascript and other things turned off, but the post box functions etc. work just fine.
Maybe Apple is heading towards no scripts running on all their products?
First Flash gets the axe, then Java is coming next and perhaps finally Javascript? hmmmm?
Smart move possibly.
Nope it's the same with it on or off.

Norton Antivirus and Mac Book Pro

I receive the same error message every time I start up my Mac Book Pro. That Norton antivirus needs to be reinstalled. I have done this several times and have gotten the latest updates but still get the same message. Is it a compatibilty problem with the intel chip?
MacBook Pro Mac OS X (10.4.6)

dralacar,
Welcome to Apple Discussions.
According to MacFixIt: Symantec has now told MacFixIt that they are working on a fix which should be available shortly.
A company representative told us:
"We wanted to give you a heads up that Apple’s recent batch of security updates caused some issues to LiveUpdate on Intel Macs. We are working on a fix right now."

How do I remove Norton Antivirus *after* I have installed Lion?

How do I remove Norton Antivirus *after* I have installed Lion?
The Norton uninstaller is a PPC native app and Lion won't run it.
Thanks.

You should run the removal applicaiton that came with your installation. Read this from the Norton web site..https://www-secure.symantec.com/norton-support/jsp/help-solutions.jsp?product=No rton+for+Mac+Products&version=current&lg=english&ct=united+states&pvid=f-mac&doc id=v64924250_EndUserProfile_en_us/
Norton AV 12 for Lion is available online.
If you want an AV program compatible with Lion then look at Intego Virus Barrier 6.

Norton antivirus says my licence have expired when switch my computer on for the first time.

I just bought new touchsmart 520-1002 ru (LN649EA). It had norton antivirus preinstalled when i started it for the first time. After few hours of working antivirus informed me that the licence have expired. But before it was like 60 days. What to do? I'm affraid of sirfing the web without antivirus protection. So i'm using iphone. May be i should return it and buy second hand mac?

Hello Karuser:
Welcome to HP's forum and your new computer. Nothing to worry about. That was a trial verson. What ever time limit they gave it has expired. I think you miss read it It flashes a reminder all the time. You can still use your computer. Until you purchase or install an anti virus software. The only thing Norton will not do is up date it's self but it will still scan your computer when you open it up and click scan. Try to get anti virus software. Titanium Maximum 2012, McAfee, and Norton are the top choices to choose from. Try to stay a way from the real cheep ones like Kerpsky that will not protect your computer. My freind installed Kerpsky asked to fix his lap top. Well I did fix it first thing I did was get it on line and run Trend House Call it found over 250 different virus. Some of the worst ones I had to manually removed. Trend House call is a free scan. Trend.com are the one who make Titanium Maximum Security 2012.
You just bought this computer Mac's are great computers but you are very limited to what you can do on them. This one will last you for a very long time ounce we get the bugs out it. My Touchsmart 600-1050 is going strong going into it's third year now. Just had it's frist full recovery done now my computer runs faster and much better then when I first bought it. Yes I had some minor issues fixed on it at first like anything you buy today is not perfect HP covored it all during the one year warranty. My recovery was performed because I picked up a new virus that no anti virus on the market could delete it had to be manually delete it but to much damaged was caused in the operating control software. Otherwise I would be still using Oginal set up.

How do I remove Norton Antivirus?

I have a full version of Norton Antivirus. I had my suspicions last year when my MacBook acted funny and it caught a virus from 2 files that came from my PC. Well, I had OS X Tiger then and installed Norton Antivirus. Now I have Leopard and no longer want Norton Antivirus. My question is how do I remove Norton fully from my MacBook? I don't want any applications or any apps running in the background from Norton. Please help! Thanks

Norton antivirus will not run on Intel Mac

I installed Norton Antivirus that I received from school but when my computer starts it errors and says it will not run on an Intel Mac. How do I uninstall. I took the program and dragged it to trash but it still has a startup item.

Hello and Welcome to Apple Discussions.
Ah the dreaded Norton word: bane of the Mac user.
The install disc should have an un-installer or an un-install option in the installer:

Have a look and let us know how you get on.

Norton Antivirus for Mac update?

My Norton Antivirus subscription has had its year and needs updating - ie more money! There's been so much talk on this site about how useless and how NV can even be damaging, is it worth updating??
If I don't, presumably the old outdated software will still be installed but ineffective?

*Mac OSX and Viruses*
There are currently no real viruses that affect OS X users. There are very small number of things that can cause virus-like behavior that can affect Macs under special circumstances. These are:
1) [AppleScript, ASthtv05|http://www.theregister.co.uk/2008/06/23/mac_trojan>
2) DNSChanger Trojan [http://www.f-secure.com/v-descs/trojanosxdnschanger.shtml]
From MacWorld, January 10, 2008:
SecureMac has introduced a free Trojan Detection Tool for Mac OS X. It's available here:
[http://www.securemac.com>
The DNSChanger Removal Tool detects and removes spyware targeting Mac OS X. Called DNSChanger Trojan and also known as OSX.RSPlug. A Trojan Horse the software attacks users attempting to play a fake video file.
Upon attempting to play the video, the victim receives the following message:
“Quicktime Player is unable to play movie file.
 Please click here to download new version of codec.”
Upon running the installer, the user's DNS records are modified, redirecting incoming internet traffic through the attacker's servers, where it can be hijacked and injected with malicious websites and pornographic advertisements. The trojan also installs a watchdog process that ensures the victim's DNS records stay modified on a minute-by-minute basis.
SecureMac's DNSChanger Removal Tool allows users to check to see if the trojan has been installed on their computer; if it has, the software helps to identify and remove the offending file. After a system reboot, the users' DNS records will be repaired.
There may be other ways of guarding against Trojans, viruses and general malware affecting the Mac. A white paper has recently been published on the subject by SubRosaSoft, available [here|http://www.macforensicslab.com/ProductsAndServices/index.php?mainpage=document_general_info&cPath=11&productsid=174]
3) MacSweeper:
From [Wikipedia|http://en.wikipedia.org/wiki/MacSweeper]:
MacSweeper is malware that misleads users by exaggerating reports about spyware, adware or viruses on their computer. It is the first known "rogue" application for the Mac OS X operating system. The software was discovered by F-Secure, a Finland based computer security software company on January 17, 2008
4) MS Office Macro viruses:
An exception to the "no viruses" is the possibility a macro virus could be present in an Office document and you could help breed that virus if you execute an Office macro. I have my default on Office to run no macros, and always check what the macro will do before I run one (never had to in 10 years of using Office).
5) It is possible to transfer a Windows virus to a Windows machine via a Mac if you copy the infected file and pass it on. [ClamXav|http://www.clamxav.com> is a free, open source virus scanner for Mac OS X that is designed to scan files that you will be sharing with Windows users to assist in making sure you don't pass on viruses to them.
6) Some people have had virus-like behavior appear on web pages due to a service (DNS) supplied by their ISP having a security vulnerability. This isn't your computer but your ISP. Nonetheless, it is a security risk. If you experience strange page behavior (e.g., ads for things on sites where you wouldn't expect those kind of ads) try putting these numbers in Network>TCP/IP>DNS Servers:
208.67.222.222
208.67.220.220
Click Apply. This is an alternate site for DNS which is patched against the vulnerability.
7) If you are using an Intel Mac and run Windows on that computer (or run Windows on a PPC Mac with VirtualPC) you are subject to all the viruses that affect the PC world and should take all the precautions that a PC user would.

Norton AntiVirus for Mac.

Greetings.
I saw Norton AntiVirus for Mac in the market. Should we buy it and install it to secure our Mac?
So far there is no virus can attack Mac OS right?
Best regards.

Norton is hopeless on windows, let alone on a mac. Don't bother. I run windows/mac on my macbook and have encountered several viruses all the time due to the large amount of things I download and not once has the virus crossed into my mac partition and I have rights to read/write to and from mac to NTFS and NTFS to mac partition.
If you are that scared use Eset NOD32 through bootcamp in windows and do a complete scan on both partitions by using macdrive to access your mac partition.

Norton AntiVirus version 10

Mac G5 2 GHz version 10.4.4
Everytime I restart or start up Norton AntiVirus's Liveupdate screen box appears. How can I turn this off before restart and start up. Please advise me.

There should be a pref, either in your menu bar extra or in System Preferences that will allow you to de-activate it. Here is what the Symantec support site has, I see you can uninstall the feature... I didn't check all the articles.

Norton Antivirus Thinks Quicktime is a Worm

Just registered here to point out that the latest Norton AntiVirus update seems to be blocking Quicktime trailer viewing by default because it seems to think it's detecting a worm. To sort it just disable "Internet Worm Protection".
If a user deselects "Turn on AutoBlock" whilst attempting to fix the approriate setting then this seems to result in constant connects/disconnects to the server - which can't be doing it any good.
n/a Windows XP

Good to know it helped.
I was actually using a download manager to get a few trailer and then view them later. When I started seeing a load of one-off Worm related warning messages whilst using the download manager I released something was up. So the investigation started...
Apple should put a message up on their website to alert Norton users - although I can't find a way of telling Apple about this. I'm going to see if I can email Norton about this to make sure they know and fix it in their next definition update.
