A Sky News investigation has found that PC repair shops are wrongly diagnosing computer faults and consequently charging excessive amounts - all whilst attempting to steal a customers' data.
Such behaviour will come as little surprise to most, but the investigation acts as a stark reminder for those a little less tech savvy.
Sky's undercover investigation made use of a notebook equipped with screen-capturing software and a hidden built-in webcam, both used to capture the work of the so-called PC repair specialists.
To make the notebook appear faulty, Sky loosened a memory chip to prevent Windows from loading. A repair would simply involve having the chip pushed back into place. Pix 4, a repair shop in Shepherds Bush, diagnosed the fault correctly and repaired it free of charge. Sadly, the following shops didn't perform as admirably:
Revival Computers in Hammersmith, West London, claimed a new motherboard would be required at a cost of £130. At the same store, Sky's surveillance software captured employees browsing files and copying holiday photos onto a memory stick. Inside one of the system's documents, another employee found fake banking login details and repeatedly attempted to access the customer's bank account.
Digitech in Putney, West London, were quick to fix the fault but were also found to be browsing through the system's pictures. A Digitech technician attempted to hide his tracks by clearing the list of recent documents, and a statement from the firm states that the photo browsing was merely an attempt to ensure working memory.
Others include Micro Anvika on Tottenham Court Road who charged £145 for a full examination, and Evnova Computers in Barbican who also claimed the motherboard needed replacing.
Then there's PC World in Brentford. Although not found to be snooping data, PC World Brentford demanded an advance payment of £230 for a new motherboard. The store has since apologised and refunded the money.
Back in 1997, PC World staff at another store found child pornography on the system of one Gary Glitter.
