A scheme offering free PCs in return for watching adverts on the computers has hit delays because of fears over fraud.
Metronomy, the company running the scheme, told vnunet.com that it would still be sending out a limited number of PCs to people who have applied, but that it is keeping a tight rein on the situation following fraud concerns.
John Thornhill, chief executive at Metronomy, said that the first free PCs will be delivered in June.
People who signed up for the offer have to agree to watch three minutes of advertising for every hour the PC is used. Households also have to use their PC for a minimum of 30 hours per month.
Most people were expecting to get their computers this month. But in an email to applicants Jacco van Seventer, customer operations director at Metronomy, said that there were a number of security issues.
According to the email the company had "received information to suggest that a minority of applicants do not intend to operate within our standard terms and conditions, resulting in the potential theft of the computer".
Thornhill told vnunet.com: "Nothing has gone wrong but we are trying to prevent something from happening.
"Thanks to posts put on message boards and forums, we found out that some people were giving us false names and addresses. This would have made it almost impossible for us to recover the PCs.
"We also discovered that people were planning to break the terms and conditions and not view the adverts.
"Quite frankly we cannot afford to get this wrong. We need to discover the extent of this possible fraud to mitigate any losses.
"We had around 30,000 applications. Now we will send out a limited number of PCs, in the single-digit figures, until we have concrete feedback.
"If we find that some dishonest people have been sent a PC at least then we can test our research."
vnunet.com has learned of customers who have received a different email stating that their free PC would arrive at the end of April. But Thornhill has warned that it is unlikely they will get a PC until June.
