which one is thebest antivirus available?

I am not sure myself. One of my friends was using Norton and the other one was using McAfee and I am using the free verison of AVG. We took a pen drive that have been infected and both Norton and McAfee were unable to detect the virus but surprisingly, my free AVG managed to detect it. So, it is very hard to tell which one is the best.

Among all the anti virus that i used, Zone Alarm is the best by far. But When i install the new version, my windows explorer is acting like crazy! so have no any other choice but to replace it, my second choice is the CA Etrust Security Suite. I should say almost the same as Zone Alarm. For me this two are my good defense for any internet attacks on my PC. Since i used this two, i didn't encounter any problems with viruses and trojans at all even spyware, By the way, for more info, this two has an Anti Virus, Anti Spyware, Firewall, Privacy and anti Phishing so, the best security that you will ever had. Cheers=)

This is just my personal preference. I prefer the Norton products. both firewall and spyware and antivirus programs ou can get it all in one.

Spyware Doctor Download good one

We use Spysweeper with Antivirus protection and it has worked very well for us. Just last night we were working on someones computer and it caught 68 pieces of spyware/adware/trojans. It does a great job of catching that stuff and getting rid of it.

I use MCAFEE and i think it is the best of all.. The worst is nortion.. Dont at all use it..

I use Zonealarm security suite and have never had any problems
