Good day. I created this thread in order to have more knowledge relating to computer antivirus.
I bought a new dell laptop about 4 months ago, windows 8.1. I have not installed an antivirus yet. Currently, i only use cds on it. My phone has been the only thing plugged with usb to it.
1. Does it come with an in-built antivirus?
2. If yes, is there any need to install any other antivirus?
3. If no, which antivirus will be the best or better than the rest? Someone suggested avg. But i've not seen it in the market. And i think of going for kaspersky.
4. I need detailed information about internet security as antivirus, and areas it covers.
I'll drop more questions with time.
