What’s a good Internet security program to put in my computer?

Hi, I want to put an Internet Security program onto my computer. Something cheap, but effective. I have Norton Internet Security, but I want to upgrade. Any suggestions?

What is the difference between Norton AntiVirus and Norton Internet Security?

Which one is more practical? I am looking for a package that I will be able to install on our 3 computers…..for under $50.00 hopefully. I have been looking on eBay and found some Norton software fairly cheap, but I don’t know the difference between Norton Antivirus and Norton Internet Security.

Can Norton Internet Security record every single thing you say in an instant messenger?

The version is 16.5.0
And I need to know whether the administrator of the PC can read every conversation in an instant messenger via Norton Internet Security?
As I’m just a standard user, I can’t find out for myself…
It’s just my NIS says it can ”examine emails and instant messages then blocks and removes threats”, so I was just wondering whether that meant instant messages could be recorded and read?

Internet Security Tool keeps opening saying I have viruses & I have to buy their package. How can I stop this?

I tries to open an internet page and ever since, Security Tool keeps popping up. When I click the red buttons (saying continue unprotected), it just keeps popping up and directs me to the page to purchase the security program. Is my computer buggared or is this program a scam?
