Unfortunately, no single "suite" will be effective. I can give you a list of standard preventive measures, and preferred applications:
Strip down all unnecessary services, features and applications:
Hardware Firewall(highly recommended) + Windows (native) Firewall OR ZoneAlarm.
Cheapest Norton Antivirus you can get (or another antivirus application of your choice) – only antivirus, NO extras.
Modified and locked HOSTS file:
Mozilla OR FireFox OR Opera instead of Internet Explorer.
Webroot Spy Sweeper OR Spybot + Ad-Aware AND HijackThis - for periodic scans.
All the Best!
