what is a good antivirus tool for Windows 7 64 or 32

Hello. I'll quote JMH from here.

You are asking for opinions.
Opinions are not always based on logic.
Most Security Applications are reviewed/ tested at intervals then made available for study.
These can be accessed via Google if you wish.
Remember quite often vested interests have a barrow to push so results may be slanted one way or the other.

You are the best judge of what suits you & your computer at any given time.
Try the free versions {one at a time} of whatever takes your fancy, see how they perform, make a decision & move on.

If / when removing same be sure to use the appropriate uninstall application from the relevant Company.

Good luck.

This applies to Firewall,but can be usefull for you.

What's the Best Anti-virus?

While I find the Free Microsoft Security Essentials decent, amd most important to me, completely un-obtrusive. You can make the stressing of any AV software virtually nill if you do some simple securing of your browser before-hand.

For example, if on IE, set your internet zone to most restrictive. Then put your banking sites, amazon and kids gaming/chat sites into the "Trusted zone" so that only those sites that you chose have the ability to run scripts, do popups, download files and 50 other things that no normal random site should be given permission to do.

I posted this on another thread.

You could read their latest report before choosing. :)

I have AVG 2011 and i have had no problems with any viruses or alike

The installer is next to useless though.

It doesn't ask (and therefore can't remember) if I want:

• A desktop icon.
• A "Start Menu" link.

Program updates reinstall the program on my C: drive, instead of the location I originally used.

I get the occasional false detection.
