Adopt better practices (use NoScript, verify downloaded binaries), keep your "Downloads" folder only for things that you are OK with deleting (else download directly to Media/Document directories etc.), do weekly malware scans etc.
If you're talking about your computer itself, just pull the plug, open it up, and suck up the dust with a vacuum cleaner once every 3 months. Every 18 months (mark it on a calendar) grab a can of compressed air and clean the insides of your computer thoroughly (the radiators, fans, etc.) since a lot of stuff will be stuck and unable to be sucked up by a vacuum cleaner.
