Norton, 360 and AVG are good, but i recommend you the UPCleaner, It is a free software but has all security function that protects your computer perfectly. As an antivirus software, it can monitor your computer and scan it to find all virus and malware, delete them and make your PC safe and responding faster. Also, it offers service of browser cookie cleaning and privacy information protection, making sure that your private account and password would not be stolen. It also has function such as router protection, Wi-Fi helper and etc.

No need to buy Anti Virus. Install Microsoft Security Essentials free from https://support.microsoft.com/en-us/kb/971606

It depends on the type of OS you use. You have to use PC security Antivirus according to the OS you have, such as Antivirus for Mac, Linux, Windows, and so on. Some of the best virus protecting software according to the AV Test rating are as follows

1. Comodo Antivirus

2. Avast

3. Bitdefender

Comodo seems to be the most trustworthy one according to the AV Test, and Avast and Bitdefender rank next to it.

Avast Free Antivirus with custom installation and settings with Malwarebytes Anti-Malware, Malwarebytes Anti-Exploit and ESET Online Scanner (installed). Browser protection and plugins Bitdefender Traffic Light, Ghostery and WOT (WebOfTrust).

Try Kaspersky or 360 Total Security

I like Norton for a PC. It is efficient and effective. Kaspersky slows down your computer completely while it does its daily update, so I don't like it. It also renews your payment automatically every year, and I hate that. Norton at least asks you if you want to renew.

Kaspersky

Yes

Windows defender works pretty well. - it's free.

Otherwise, if you get a virus/ Trojan, set up a computer back-up so you can then perform a system restore - also free.
