AVG is an adequate AV product. Personally it installs a little more than I would ike, toolbars, for example, that can be tedious to remove.
I use Avast Free and it does a nice job for me. There are other free AV products available as well. Here are some links, if interested.
Anti-virus software will help detect, cleanse, and erase harmful virus files on a computer, Web server, or network.
Unchecked, virus files can unintentionally be forwarded to others, including trading partners and thereby spreading infection. Anti-virus software can scan the computer memory and disk drives for malicious code. They can alert the user if a virus is present, and will clean, delete (or quarantine) infected files or directories.

- 30 day free trial.Installing a new AV product.Do NOT uninstall any existing anti-virus product yet!
It is strongly recommended that you run only one antivirus program at a time.
- Download the new Anti-virus product to your computer.
- Save any work. Close all applications, especially your Internet connection.
- Uninstall any existing anti-virus product... Use the AV uninstall option if available.
- Reboot your computer, if not done during the uninstall.
- Install the new AV product... following installation instructions.
- Check for updates to the new AV product, if not done during install setup.
- Run a full scan of your computer.
Having more than one antivirus program active in memory uses additional resources and can result in program conflicts and false virus alerts.
