There are two good ones for free, Avast Antivirus Home Edition y Avira Personal Antivirus, the both need a registration in the webpage and they send you the activation code, then you will have free updates, etc. I put the two links below.

Disable Windows firewall if it鈥檚 not disabled automatically.

If you download another firewall.

Also have some spyware/adware removers like Ad Aware SE Personal and Spybot-S%26D.
