What is the best anitvirus software for Windows XP?

Answer 1

AVG Free is the BEST

Reasons,

1. It is 100% free

2. An option to Scan USB devices automatically

When you plugged in a USB device to your PC, AVG will start to scan it automatically

3. Resident shield

Auto scan, files and folders when you open, (if you double click a virus, no harm to your PC, AVG will block it in a second with a warning and will ask from you to delete)

4. Auto update with less data usage

I use AVG Free. I have monitored its weekly auto updates and it use approximately 500KB per week for update

5. No affect to system speed

I haven't feel any affect from AVG Free to my PC speed (I'm using Core 2due, 2GB ram, Windows 7 ultimate)

6. Version update 100% free

When AVG release a new version, your older version will ask from you to auto update for free
