But, he said he wants the best and thus he wants to pay.

I use malwarebytes' anti-malware its completely free unless you get this chip that does a scheduled scan but you don't need it because you can just start a manual scan. This pretty much saved my whole computer and i would recommend it to anyone.

I haven't played musical antiviruses in a while, but I know enough to tell you look for one that uses heuristics. This means it can detect threats it doesn't know about yet.

I use Kaspersky Anti Virus 2009, it is a leading anti-virus software and Internet Security software solution for your home computer or business.

lot of antivirus sofwtare available like norton ,mcafee etc but i prefer to download full antivirus software pc security advsior cause it's seem to be good going for me from last two months and mine pc show best efficiency

Linux

I have my firewall (which alerts me when I log onto a suspected attack site) with Avast! Antivirus, Spybot Search & Destroy, and Malware Bytes Anti-Malware.

Avast detects a virus before it gets to my computer. It has an on-access scanner and the alarm goes off if I go to an infected site. Mine's paid for. It's not too expensive for a year. I like it because I don't have to go out and buy anything at the store. Just download it if your Granddad wants it.

McAfee is also good.

The "best" antivirus protection is a free one that works well and goes easy on system resources.
