Should I remove my old Anti virus protection before I install my new one?

by on June 17, 2012

I want to install my new anti virus, should I install first or get rid of the old one? Should I turn the Internet access off while I am installing?

Thanks!

Yes.

You should definitely uninstall your old anti-virus before installing the new one.

Edit: Who’s the smartass jerkoff that keeps thumbing down VALID answers?

It is possible to run more than one Anti virus at a time but I personally recommend removing the old one first because they can interfere with each other.

if its a new version of the same one then no it will just upgrade…but if its a totally different brand then i would definately remove the old one so the old one not trying to block new one and it runs smoothly

If you turn the internet access off, then you can uninstall the old one first. If not, then install the new one, and then uninstall the old one. But don’t leave both on there because that will just cause problems. Good luck!

If it is a different program it will tell you to un-installl the old program before proceeding.

I would remove the old program and restart your comp before going forward with the new program.

You need to disable the old one for sure. If you are not planning to ever use the old one, uninstall it before installing the new one, but if you want to keep it for some reason, disable it. NEVER run more than one anti virus at the same time. You can do a scan with one, then disable it and do a scan with another one, but not at the same time.
Internet access while installing? Well, it’s not a must to turn it off, but what do you have to loose, if you turn it off?

I think you should do it, as a matter of fact most of the anti virus that are installed automatically uninstall the anti virus that remains on your computer, but not everyone, my advice it’s that you remove your old anti virus, it is true that 2 or more anti virus could work simultaneously in one pc however they won´t function properly, if you want more protection you could install only your new anti virus dismiss the old and installing an antimalware like malwarebytes or an antispyware.

yes definately, you should only ever have one anti-virus active at any time

Yep, uninstall the old one – as it has been mentioned, two will most probably conflict with each other.

What is your old AV? Sometimes you may require a special removal tool if you are having troubles uninstalling. If such a tool is available for your old AV, I recommend using it regardless of whether you are having troubles or not.

EDIT:

LOL! This appears to be a free-for-all thumbs-down-fest. Hope you can find a good answer here somewhere :)

Let me expand on my answer – while it is possible to have two AV programs on your computer (with one *not* running in real-time, of course), to save any confusion (if you have little knowledge of AV software), I highly recommend only having one.

Of course you can have 2 anti-virus programs on your computer – you just don’t want them both running at the same time.

You will need to:
- download the new program
- install the new program
- disable the old program and stop it from running, even in the background
- set up and run the new program

Internet access does not need to be turned off : )

HTH!

I think if it is a different Anti Virus product, you should remove the old one to prevent conflict (thinking each other is a virus).
If it is a newer version of the same one, you should also remove the older version one.

You don’t need to turn your Internet access off unless it tells you to.
If it tells your computer needs to restart, I suggest to turn the Internet, Safari, Firefox, etc. window(s) off before you click “restart computer”.

START INSTALING NEW AND WEN ITS INSTALING UNINSTAL OTHER ONE AT THE SAME TIME

Nils June 17, 2012 at 4:23 pm

Yes, but you should
(a)download the .msi or .exe of the file (without installing the program)
(b)unplug internet
(c)uninstall old program
(d)install new program
(e)plug internet back in
(.f.)run updates on new one(gets current virus definitions)(some programs don’t have this)
(g)run scan/search on new one
(h)set up your program to scan automatically when you want it to
(i) ENJOY YOUR SOFTWARE!

YES

most of new anitvirus do not get install if any old one is installed ,

and if it is original then there is no problem to keep internet on..!

harry potter June 17, 2012 at 6:47 pm

install the new anti virus and simultaneously uninstall the other…..if you have winrar or winzip then no need to be afraid. uninstall the previous one and then install the new one and let winzip do the rest

Peyton June 17, 2012 at 6:55 pm

YESSSS!!!! IF YOU DONT YOUR COMPUTER WILL SLOW DOWN TREMONDOUSLY. BELIEVE ME, BEEN THERE. NOT FUN!

If you are just renewing the same brand of anti virus the updater will recognize the old version and delete it. If for some reason it doesn’t, you can delete it manually after you are finished..
If you are changing brands, like going from McAfee to Norton, uninstall the old one first or you will end up with a ton of conflicts. You definitely don’t want two anti virus programs running at the same time.
Leave the internet on during the process unless it prompts you to disconnect. The program will have to go out and look for updates, patches and validation numbers etc. while it is installing.
