Here are some ideas:
1. A resident firewall (ZoneAlarm or Sygate---both are free).
2. Spybot Search and Destroy.
If you have additional hard drive space, there are additional anti-spyware applications you could install, but Ad-AwareSE and Spybot should find almost all the malware out there.
Connecting to the NET without a resident firewall is extremely dangerous in today's world; fortunately, there are several excellent firewalls from which to choose.
Whereof one cannot speak, thereof one should be silent.
