I have Norton anti virus 2007 already installed as an offer on my laptop when I bought it. Now the subscription has expired and I dont want to have a paid renewal for that, instead thinking to go for free 90 trials of McAfee or some other ones. Now my question is can I install McAfee or any other anti virus software without removing existing Norton anti virus. If its not a problem, will there be any problem having two anti virus softwares on computers. Also please let me know which trail versions are best if the McAfee that I chose is not okay for you. Thanks in advance

It is possible, but not recommended.. They might interfere with eachother and erase important files if one tries to acces it :D So I wouldn't do it :D Have a nice day ^^

As far as I am concerned we must always use one safe and protective anti virus in our system, we must never use two antivirus, because instead of protecting the system, each antivirus will not work assuming that the other must work. Hence, if you want antivirus and your system to be protected, go only for one which ever you think is better. Having two anti virus in your system is like maintaining two guards before your house for safety, and both not working thinking the other will work. Hence, think wisely and use the one which you think is the best in giving protection. and at the same time you can use other softwares instead like spyware doctor or firewall etc, but not other different virus.

in all my ten years of building,repairing and upgradeing computers, i have never read so much rubbish. i have been running 2 antivirus programs and 2 anti spyware programs in all of my 5 computers, and i am running 2 antivirus programs in my laptop. granted you cant do this with all antivirus software, but avg an avast work perfectly well together, norton and avg no, panda and avast no,, panda and norton have a conflict problem only because they are both heavy resource users. all you need to do is test different antivirus programs until you find 2 that work well together. and just so you know i am a fully certified I.T. Tech.

Hi rocky, I have written what i have heard from my friends, I am also a btech engineer but I am a fresher, for this you neednot write so much harshly, your first sentence was quite hurting. If this is wrong its ok, never mind, its only my opinion there is no rule that you follow it, and i think people do participate in discussions. anyways, i am very sorry to tell u , your first sentence was very very hurting. this may be rubbish for you who is an expert, but you cant expect the same from a novice.

i find norton antivirus very heavy for the sistem, for my pc i use mostly 3 freeware programs that works great : AVG Antivirus 8.0 SuperAntiSpyware CCleaner take a look at these three when you have a bit of time...

not opposing, but only saying that CCleaner doesn't count as anti-virus or even a security software of any kind. may be it can be regarded as a privacy protection tool but that too is a bit heavy on description. :-P ccleaner is a very good s/w of it's kind.I use this myself and I recommend it to anyone and everyone but it's just not relevant here. avg is try-worthy I would say.

heavy for system means it's a bit resource-hungry. makes your machine slow sometimes. norton is very much infamous for that. :-p

hi there! my friend worked for for Norton before & I myself is familiar with some anti virus protection for the pc since I also troubleshoot internet connection along with AV. each new computer has an antivirus installed to it & it's not necessary for you to sue it especially if the subscription has ended & it's asking for some money to renew. It's always your choice of what AV is good for you. My friend who worked for Norton did assure that NAV (Norton Anti-Virus) has heavy components whereas it could take more memory of your laptop. you CANNOT install Norton & McAffee at the same time or any 2 different anti-virus. one way or another one would not function because no 2 software with the same feature can work in one computer. also, even if you try to install McAfee, you will get a prompt window informing you that you cannot proceed. Mcafee is better than Norton, but one thing i've noticed about McAfee is that it has strong firewall that conflicts the internet connection. Norton on the other hand has strong settings that blocks the entire internet connection. There are a lot of Antivirus out there, in fact you could download them for free. try kaspersky, i heard from co-technician that he is using it & it works fine foe his computer. on the other hand, i'm using the latest AVG in my laptop. hope this helps.. and besides, you need to unistall one AV to free up your disk space for the AV you want or prefer.

Thanks for the information. As Norton employee itself assured that it slows down computer which I also feel sometimes my laptop is too slow in doing some tasks, I shall now go for other AV and see if everything works well.

i think one factor why Norton slows down the computer is that it has heavy files/components where it takes much of the memory. try to check Anti Virus that you could download for free. this is very convenient since you don't need to worry about subscriptions. and you could use the money for other important things. :)

You can Install two different anti virus on your Computer . But Only One will be Active at a time . Some time Other Antivirus demands to Uninstall 1st . So its better to Install one Antivirus at a time. ist of all you make sure confirm which antivirus is suitesd to you .

Unless you have alot of time to figure out the conflicting messages you will get, I wouldnt run more than one AntiVirus program. If you decide to not go with Norton, make sure you use the complete removal too available at their support site. At their Symantec site, go to the support section and do a search for "Norton Removal Tool" As for advice, most users are happy with AVG or Avast, and they are free. I myself use BitDefender. Hope this helps.

Thanks very much for this info. I was wondering how to remove Norton from my system as I couldnt find the uninstall option in my program list.Someone suggested to format the system for which I was scared, now relieved.Will check the norton support section.

Yes you can. It depends if you install compatible antiviruses. Ive tride NOD32 with Avira and works great. Even if both of them were updated, there are viruses that are detected with NOD32 which cant be detected by avira, and vice versa.

I have not tried installing more than one anti-virus program on any of my computers. I believe some software will conflict with each other, because usually such software does active scanning of any files downloaded into the system. I can't imagine how two or more anti-virus programs will be concurrently at work scanning files for virus as they come into the system. Once a friend of mine asked me to help her install Norton Anti-virus onto her PC. I didn't know what else she had previously installed, but as I was proceeding with the Norton installation, a message came out saying that there was another anti-virus program installed, and that I will have to delete that program in order to successfully install Norton. So my guess is having more than one anti-virus program active on your PC is probably not allowed.

I heard some people say it's better not to install two anti virus softwares for the same computer because they may be a conflict. However, I do install two anti virus softwares. One of them is small and the other is a big one. I don't find anything wrong with it. My computer keeps virus free until now. I love China

You can install two different anti-virus software but only one will be used and detected in your Operating System. It doesn't matter whether it be two or more, as your the security section of the Operating System only recognize anti-virus software to use. As with the new anti-virus to install, from my experience, I don't really have much impression with McAfee, it is easily by-pass by worms. I recommend you uninstall the previous version of your anti-virus software and install a new one. If your current anti-virus is Norton and you like to install another anti-virus software, your system will still recognize Norton as the system's anti-virus program it will ignore the new one.

You will need to Remove Norton before installing McAfee, reason for this is that the two programs will work against each other and make your system real slow.

Yes you can use not only two can use lot of anti virus software if it supports. I'm using Norton, AVG, Spy bot, C Cleaner, Spam blocker and more softwares to protect from virus and spyware and I'm also using adware remover too.

try nod32. that should be your best choice regarding anti-virus. now we are not supposed to promote piracy here, but you can get pretty much anything on the web for free. hell with the ethics. if you want this, you acquire this by this or that. that's merely a suggestion. have your own go at this. I won't recommend using two anti-virii( I thought I'll use the plural of viruses in here. ;-) ) on a single pc as they might interfere in each other's tasks. Just think of caging Stephen Hawking and Roger Penrose in together and you can imagine what happens there is pretty much the case here. :-p Never mind.

Honestly, I would be surprised if your computer hasn't hanged even once with 2 (or 3) anti-virus programs installed.

As I think it's better to Install one one Antivirus in a system because the Anti virus Programs are very strong & hey are compatible with other antivirus Programs. Better to Uninstall the Norto in ur Lap & Install new Mcafee or anyother.

it better not to install two different anti-virus in a same operating system,coz every antivirus has its own virus extension name to detect,it may conflict, may be they might found one another as a virus,by conflicting each other,they may delete system files.

They can conflict with each other especially if they are running at the same time and trying to scan the same part of your computer; also, they will use up a lot of your system resources so your computer might seem a little slow. Trend Micro Officescan is a business product usually seen in enterprise client/server machines. AVG Antivirus has a good reputation as an antivirus scanner - if you need added protection, use an antispyware scanner such as Spybot or Superantispyware
