I've been using Trend Micro for about 12 years now and have watched it grow from a signature based antivirus to a cloud based antivirus. Yes I've tried other antiviruses including Norton but have always come back to Trend for the reason it's so simple to use, yet if you want to maximise the most of Trend you can. Norton/Symantec is really good when it comes to the business side of things no question there but when you're looking at a consumer side have always gone for Trend. Trend also has/still does (from what I've seen over the years) the best web filter/shield out there. Most people will say that people say that you can just ignore the message and continue and hope that Trend will block it, but to me if that ever happened I'd just power on the virtual machine and go for gold playing with malware in there as I do in the Malware Hub here on MalwareTips.
Trend Micro is a little heavy on ram btw Norton is lighter.(I use Trend Micro 5 years ago I have bad dream on it
)
I do agree with this. Trend was very very heavy on ram years ago but since moving to the cloud I have never even noticed any system impact on performance when it comes to the Trend.
I also love the features it comes with. Not sure about Norton as it has been a good year since I tested their products but when you buy Trend you're buying the product but also buying other features like a password manager, can protect up to 6 devices/computers can protect and block bad websites that you don't want your children to go to.
But at the end of the day it comes down to preference. Why not give Norton a go for 30 days and see how you like it. You might end up liking it alot or might just like to stick to Trend.
The choice is yours
