Probably the most common scam: You receive an email asking to review your bank details for some reason such as a 'Security review of all accounts'.  IGNORE IT!

No reputable bank or other financial organisation will send you an email with a 'click here' type link to correct / update / review / confirm your account details.  If you are not convinced it is fake then phone your bank to check or check your account online by your normal method - NEVER click links in such emails.

Some typical emails:  (From.... Subject)

• NatWest Online Bank....   Natwest - Security centre - review of your account activity
• Mr David Walcott....   THIS IS NOT SPAM,SALES OR SOLICITOR
• Egg Internet Banking....  Your Egg Online Bank Account Is About To Expire
• Halifax Online Banking....  Halifax Mail - Reactivate Your Account
• Barclays Bank PLC.... RE: PAY DAY US$800,000.00
