Any emails you get offering you large sums of money, or telling you you've won millions, or your long lost rellie in Oooboogooboo land has left you millions but send me your bank details should just be deleted.
Another email you may get is spoof ones from any number of different banks, building societies, eBay and paypal. These will usually contain a link within the body of the actual mail and you will be taken to a site that will ask you for details of your bank/ebay/paypal account including passwords etc. Delete these too. Banks etc will NEVER ask you for your details via email. If in doubt you can send ebay spoofs to
[email protected].
If you want to check any details that you have been sent via email do not click on any links within those emails but go directly to your banking/eBay web site. Rarely these spoof mails can be telling the truth - For example, I had my ebay account hacked and I thought the email telling I had changed my password was a spoof. Sadly, it wasn't but I went via the ebay link in my favourites list to check and not via a link in the email because there was no link
You'll get to know which ones to dismiss immediately and which ones to check out
