The best anti virus is being able to do it yourself.

Task manager is a big help though xD

But then cleaning your computer manually is somewhat annoying. Also, Task Manager utterly fails to help clean up stuff. I use Autoruns and Process Explorer, both available from Microsoft. They own rogue processes and boot entries far better than Task Manager and msconfig ever could.

Also, ClamAV is pretty good from what I've seen of it, my dad uses it in conjunction with a spam filter on a Linux server.

Them nasty IE toolbar plugins are a good start as well.

I use AVG Free Edition and I think it have worked great so far. Before I got my own computer we used to have Norman and later Norton, which both sucks imo.

I use AlYac. (AlMedicine?)

I use Norton because my school requires it to access the network. Hear my tale of woe about it...

Avast! Home Edition and AVGFree are both free, and it's not like Linux doesn't have any security holes. It just doesn't have enough users to make it a valid target.

I use Avast! Home Edition, but common sense is the best anti-virus.

The best antivirus is not downloading weird stuff and being careful to avoid getting viruses at the first place.

Debian/OpenSSL fiasco *cough*

Norton practically IS a virus once you run out of the subscription. Heck, I'd say it's worse than most viruses, since it's totally overt, popping up and not listening to your "remind me again in 15 days" reactions, it also blocks your ports when using new programs, and slows down your computer like crazy. You cannot simply uninstall norton, you will mess up your computer if you do, you must use the Norton Removal Tool. Norton is a virus. I managed, after being forced to reboot my computer 2 times, to remove it and replace it with AVG

Other antivirus should detect it:
Alert! Norton is running on your computer! What do you want to do?
· Remove it · Put in quarantine · Ignore it

Same with mcaffe(<-- however that crap is spelled...) I couln't even delete it w/o downloading the full version!!....... And I had my run in with norton too... worst scan/antivirus/antispam ever!

nod32 or avg. nod32 better but avg feels so bubble-gummy and nice lolz

Nod32 on my old computer (loved it) and have had no antivirus on this computer (I've had it for about 2 months). I downloaded the Kaspersky trial the other night for shits and giggles and it found no viruses. Kaspersky seems really good after my day of use.

If that is the only flaw you know of you haven't even played with Linux.That is the only bug that has gotten out to everyone and now windows lovers are going Linux sucks cause of Openssl and such.Really there is more then just that.Plus there are enough users of Linux to make it a target,in the server world at least.I bet you didn't know there is over 100 viruses for Linux did you?

lol, over a 100 viruses. Are you sure most of those aren't just flash vulnerabilities and web exploits which work on any OS?

There's a difference between a security hole in the desktop and a security hole in the server. The desktop user reads e-mail, surfs the web. They actively seek new content. Servers don't work quite that way. They aren't downloading many things.

Heh, I use Kaspersky. I don't get viruses though.

Yes dumbducky I am sure.It is a bit hard to get them though with how the package managers are used.Infact if google a bit about this you will find the news on Linux viruses.
Mac also has viruses(mac users love denying it).

Mac viruses are generally targetting windows software on the macs, and since there is such a small population using them, no one wants to make a virus for them.

"Embarq Online Security"

It came with my ISP, Embarq, and it has like pretty much everything I need: a firewall, anti-virus, and anti-spyware/adware/other malacious crap. I don't pay anything for it.

Except the cable bill.
