Use an antivirus program e.g. AVG, Norton, Microsoft security essentials.
Don't open attachments from emails you don't know or trust.
Logout from websites when you have finished.
Ignore telephone calls that say they have found errors on your computer, often the say they are from Microsoft, they are bogus.
Don't use registry cleaners or programs that are supposed to speed up your computer.  These programs often run on start up each time slowing start up.
Only put information on social networking site that you wouldn't mind on a poster on a notice board in a town.

Oh and one important thing, back your data up (files and pictures particularly), just it on a pen drive or a disk will do if you have only a small number of important files.  My documents and My pictures are generally the important places you will want to back up.
