Computer systems, much like helicopters, require preventive maintenance and component upgrades. The recent worm and variant programs that have brought down many systems in recent days, but this is
easily prevented. In fact, Microsoft provided a patch for these vulnerabilities LAST MONTH!
There are very few "true" hackers that have the programming ability and inside knowledge to get into systems. Most malicious applications come from amateurs that download tools and scripts, and eventually put them into a program. They don't really understand them, but they can follow a cook book. There are many websites that post how to build virus for "educational" purposes (i.e.

IF YOU HAVE A MAC, UNIX, OR LINUX SYSTEM:
Your Operating System vendor has their own tools available to keep your system up to date. MacIntosh has one of the best tools for that because it will update your application software at the same time you update your OS.
OTHER RECOMMENDATIONS:
Even if you only use dial-up, you should have a personal firewall at a minimum + antivirus software. Windows XP has a basic version that you can turn on; it will work for your purposes. AOL Version 9.0 was released today, and it includes antivirus and firewall capability (for those with Windows 9x, Me, and 2000).
If you have broadband (Cable Modem, ISDN, IDSL, ADSL, SDSL, Satellite, Frame-Relay, Fractional T-1, or T-1), you need a more advanced packet-filtering STATEFUL firewall to protect your computer(s). There are a lot to choose from; just get one. Symantec has some nice packages that are inexpensive.
