use Firefox with no script plug in if you don't your a *** idiot.
It helps but there's no way to be 100% protected/safe. But definately take every course of action to protect yourself and nip these potential hacks in the bud.
This includes but is not limited to:
Up to date and functioning antivirus
Spy/Adware scanner and remover
A more secure and fully patched internet browser (Firefox)
A script blocking plugin for said browser (get No Script, whitelist based is safer)
Using on-screen keyboards for password entry
Not giving your account information to anyone
