Best free antivirus?

On the advice of Y!A users, I downloaded Anti Virus Shield, but it only works if there are no other antivirus softwares installed in the pc.

Is it worth throwing out AVG Free and replacing it with AntiVirus Shield?

Your time spent answering this question is deeply appreciated.

I have used AVG Anti Virus, Zone Alarm Firewall, Spy-bot Search and Destroy and Ad Aware both spyware killers for years. They are all free for personal use and I have had no trouble with Viruses Trojans etc. AVG does not slow the system down as much as some other products and Zone Alarm allows a lot of personal configuration unlike the Windows Firewall. They can all be downloaded from the following link. http://www.computeractive.co.uk/ On the home page select downloads and then the appropriate category.I also use Windows Defender from the Microsoft site. It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. You should run A/V and anti spy weekly. Hope this helps.

AVG is the best in my opinion
Avg is the best free virus protection on the market, hands down. You should keep avg.
I love this one: www.CyberDefender. com. There you download Free 2.0. Good luck
