Here you can find a collection of full internet security suites. These programs usually consist of the following software:
Anti-Virus
Anti-Spyware
Personal Firewall
Anti-Spam

Many PCs today come with either Norton or McAfee Internet Security products. However these programs often only have a limited license (typically 3 to 6 months). While these are competant products I cannot recommend them. I have worked with hundreds of PCs with these products installed and often find that unless the PC is quite high spec they tend to bog the machine down slowing it down considerably. I have also found that upon uninstalling these products there can often be problems and need to be cleaned up manually. I would recommend ditching Norton and McAfee and installing one of the prducts below.
