Unfortunately there is no quick fix solution, but there are a few things you can do:

1. Make sure that your computer is protected by a Firewall. Not just the
   Windows Firewall, although it is better than nothing. There are free
   solutions available like the Comodo Firewall and the free version of ZoneAlarm.
2. Antivirus software, most importantly one that is up to date.
   Symantec Norton AntiVirus 2008 has good ratings, although I
   find it has to be tweaked to prevent it from slowing down your
   system too much with its real-time scanning.
3. Antispyware software – experts recommend having two of these
   (unlike antivirus or firewall software) – A commercial one and a free one.
4. Antispam filters on email – email is one of the ways in which malware
   can get onto your system, especially if you use Outlook.
   If you use web-based email like me, make sure that images
   inside of messages are disabled by default.
5. Watch where you browse. If you must go to dubious websites, use a
   sandbox or virtual machine of some sort. Even for normal browsing,
   something like McAfee Site Advisor is indispensible – I use the free
   version, but the McAfee Internet Security Suite 2008 includes the
   Site Advisor.
6. Download files from reputable websites like download.com. On other
   websites Site Advisor can really help to check if a site has dubious
   downloads or not.
7. If you don’t mind trying new things, switch from Internet Explorer to
   another web browser like Firefox or Opera. Firefox is constant being
   updated for a safer browsing experience.

Although it is possible to choose the best Antivirus and the best firewall and add the best Antispyware, I find it more cost effective to use Security Suites, which usually include anitvirus, antispam, antispyware and a firewall. For my older PCs which I don’t use much, I mix and match freeware Antivirus like AntiVir or AVG Antivirus, along with freeware firewalls and antispyware.
