1. Software can't clean hardware. That's a task for you.
2. Nothing special to do.
3. Keep current with updates (from Microsoft, Adobe, Java, Mozilla,antivirus, whatever you have installed). Quite a few updates are meant to fix bugs that makes their products insecure.
Things to do:
- run antivirus (like Avast, AVG, Norton, McAfee, Kaspersky)
- scan for spyware once in a while (MBAM, SAS)
- use the security features in your browser and e-mail program
- do NOT click on suspect links in suspect emails
- do NOT download illegal music and movies using torrents
- do NOT Yes in any popup if you don't know what you say Yes to

I've heard that one should do the regular things below for maintaining a healthy PC:
1. maintain the hardware healthy and clean (any software for this?)
2. maintain regular settings not to be changed by malware. (anti-malware?)
3. Strengthen and harmonize software installed in the device to avoid conflicts. (How?)
Any help?
