I've just been a victim of online fraud and theft

you are entitled to a free credit report once a year--i encourage everyone to look theirs up, from all three agencies. i do it every year when i file my taxes, seemed a good way to remember.
also, be very careful about websites you use to shop and NEVER give out personal info when you receive an email requesting those things. very often it's a fake email (from paypal or ebay for example)--NEVER use links to go to sites from those emails. also, most reputable companies (such as those two) will not ever send an email requesting info. we've gotten fake emails before from 'ebay' and sent the email on to their fraud dept.
also, legit co's will send to your real name, not a blanket email to 'customer'.
