Now that your system is clean, here are a few things you can/should do to minimize your chances of future virus/malware infections:
1. Enable Windows Automatic Update function to keep your system as up-to-date as possible with the most current Microsoft security and bug fixes.
2. Stop using Internet Explorer as your web browser. Because IE is so closely tied into the Windows operating system itself and contains so many security flaws, switching to another browser such as Netscape, Firefox, or Opera will reduce the avenues through which spyware/adware/hijackers/etc. can infect your computer.
3. Install preventative utilities such as SpywareBlaster and SpywareGuard (links are in my sig below), especially if you absolutely have to continue using Internet Exploder. These utilities protect areas of your system known to be vulnerable to malicious attacks. IE-SPYAD is another helpful tool; it can be downloaded here:

4. Tighten up some of Internet Explorer's existing, default settings to make it more secure. Some info on that can be found here: http://tomcoyote.org/ieoe.php
5. Obviously-install a good anti-virus program and enable its "auto-protect" and email-scanning features.
6. Install a stand-alone firewall program such as Zone Alarm, Sygate Personal Firewall, or Kerio Personal Firewall, or purchase the "Internet Security" packages offered by Symantec and McAfee.
7. None of your utilities are of much good if you don't check for updates frequently; updates for anti-spyware/anti-virus programs can be released as often …
