Looking for the right Antivirus for my neighbor!

So, I just recently helped my neighbor put Windows 8.1 on her laptop. She has no antivirus on it yet, as she is not computer illiterate. I use Comodo on my Windows 8.1 desktop. What user friendly antivirus does anyone recommend?

I use Avast Internet Security.
I have no viruses or malware on my computer.

Okay. Well, her ISP uses Norton. She bought the package where she is to use what her ISP wants her to use. Is Norton okay?

It is ok, no the av solution of my choice but definitely ok.

I am thinking about going back to Avast! myself. I haven't made up my mind yet. What do you all think?

I personally use GData Internet Security together with Malwarebytes. Like one can sense when ready my earlier post I don't particularly like Norton. Avast! is not bad, I would definitely prefer Avast! over Norton, at least on a private PC.

I use Defender, works well and the price is right

Windows 8.1 comes with a good antivirus built in called Defender, but it is absolutely terrible at other malware and PUPs (there is a difference between all three). In using some of these AV programs, I've found that they are known to cause many problems with Windows, and if not today, a bad update is on its way down the road. I am sure there are good ones that are well known to be stable, but I can't point to which ones exactly. Currently, I myself use Defender and a very good free scanner called Malwarebytes that I use every week or so to do a quick scan to keep clear. Concerning both Norton and Avast!, they've both wreaked havoc on my systems before, though Avast! is a fair bit more kind (better). If you only had those two options, my vote is Avast!

The main thing to do is never visit questionable or unknown sites, but that is easier said than done. If you search for things, generally you're going to want to open unknown websites in order to find what you're looking for.

You've pretty much opened a can of worms. Nothings gets computer enthusiasts more enthused than discussions about AV programs.

Well, I am thinking about using Avast! again. I currently use Comodo on my Windows 8.1 desktop.

I think the main objection most have about Norton is that is resource heavy which it can be "IF" it is running on a system with marginal performance specs and the user does not disable the features that don't have anything to do with protection like pulse updates, disk defrag and temp file cleaning, idle time optimization and all those things that have nothing to do with protection. On the other hand, Norton is among the best or close to it when it comes to protection which is the important thing.

I have been running a version of Norton for about 13 years. From 2001 to 2010 I ran Norton AV on a Compaq XP desktop and from 2010 to current, Norton 360 on the same machine. In 2013 I purchased a new HP Windows 8 desktop preloaded with Norton Internet Security which I converted to Norton 360 several months later and I have updated this desktop to 8.1 with all current updates including optional. Throughout all these years I have never had a conflict with any updates whether it be Windows, Norton, HP or any installed software. Best of all, I have never had a virus or any malware and I surf the net rather recklessly. A couple of months ago I purchased a new HP 8.1 laptop which I immediately uninstalled McAfee and installed Norton 360. Again, no problems whatsoever.

I decided to post this because I get kind of tired hearing Norton get slammed when it is actually a very effective product with many millions of users worldwide and if the user takes the time to get to know the product and disable the features that don't have anything to do with protection I think they will be surprised at how efficiently it runs.

And by-the-way, in all the years using Norton I have never disabled anything to get updates, I don't even turn off tamper protection to do a restore although it may be a good idea.

If the Norton product is free and the users machine has reasonably good performance specs and the user disables the unnecessary features I would have a hard time advising them not to use it.

That's it, I have said my piece. I am sure there are different opinions and I respect that but all I can do is relay my own personal experiences over many years with several different machines and different versions of Widows.

I never did like Norton either. I never felt it even did a good job at protecting you from bugs.

Norton has better online rating than defender ,according to what I read ,I just installed it on a friends new i3 desktop it seems to be fine so far , but I use defender on win8.1 and win7 starter

Avast Premier that's what I use can't go wrong.
