Don't use the most common browsers, for a start, they are the ones that the criminals attack first.
Rapport has been going for years. I recommend it.
Change passwords from time to time, at least 6 monthly, don't use real words.
Use a random password generator, then change it's output by a couple of letters.
Internet security is helped greatly by using common sense, and never using a password for more than one application, especially where money is concerned.
Some people I know use the same passwords for email accounts, forums, ebay etc.
