Just recived this from the Lloyds TSB bank Dont get caught out.

A small number of customers are receiving unsolicited phone calls from companies offering to repair or upgrade their computer. These callers turn out to be fraudsters who install software which allows them to take over the customers computer and have access to Internet Banking. HELP STOP THE FRAUDSTERS Don't allow someone who calls you unexpectedly to access or install software on your computerDon't disclose your Internet Banking password or memorable information to anyoneWe will never ask you to transfer your money to another account due to fraud or any other issueWe will never make an automated phone call asking you to approve a refund into your account For more information and a video example of a suspicious call, see our Online Security Help and Guidance.

                                                                                                                                                                             

I had one of those the other day. He rang Mrs AJ then me. Indian accent.   I just asked him if he thought I was stupid ?  He hung up. 
However I can recommend someone if your computer needs attention  AJ
                                                                                                                                                                             

Please transfer all your life savings into my bank account.

I will then fix your computer, remotely, from my yacht moored off my private island somewhere in the Caribbean.                                                                                                                                                                             

My mate, who is a network/IT manager had one of these calls. He explained in great detail and at length why his PC was not vulnerable, after about 20 minutes the scammer hung up!                                                                                                                                                                             

Disable any "remote access" feature on your PC and do not download anything from anyone with a Nigerian accent. You have not won $10,000,000 from an over seas lottery and you are not related to an African prince who needs to move money through your bank account.
Install Norton Internet Security but get it from PC World when it's at half price.
Do not open emails from JP Harley, they are usually demands for pies or icecream                                                                                                                                                                             

I usual say I don't have a computer.
It's good approach for everything cold caller-ish to deny all terms and conditions.
If it's for utilities (gas, water, electricity) I say I live off-grid.
The most entertaining though is denying I have a telephone, you can almost taste the initial confusion
                                                                                                                                                                             

I say I can't talk right now, and could they call me back later on a different number.
I then give them Steve's number...                                                                                                                                                                             

That's took XK, I just give them your bank details :-)                                                                                                                                                                             

My son tells the claim solicitors that he was in an accident but he die from his injury's it take some a few mins to notice that there talking to a dead person
                                                                                                                                                                             

I'm going to nick some of these replies for future reference.  Very funny!  :)
