There isn't any best anti-virus. No anti-virus is flawless, so that it can be termed as the best. Again, all the anti-viruses detect and remove 'in the wild' viruses (the viruses that mostly attack personal computers), so it's safe to use anyone of them.

It really matters HOW you use your anti-virus and not WHAT anti-virus you use. Your anti-virus should

1.have a good real time protection

2.update regularly

3.remove infections effectively

Again, you should take care that your anti-virus stays on all the time, is up-to-date, and scans your computer every week or so.

Here are some good quality anti-virus software, out of which you can choose anyone you like.

Not free: Kaspersky, BitDefender, TrendMicro PcCillin, Norton, McAfee, Avast! Professional, AVG Professional, AntiVir Personal Premium, NOD32, F-Secure

Free: Avast! Home, AVG Free, PC Tools Free anti-virus, Comodo anti-virus, AntiVir Personal Classic, ClamWin (with WinPooch)

:)

If you urgently want an anti-virus, get anyone of the free options mentioned above. They work really well. Just do a Google search and you will find their home pages and download links.
