Microsoft Malta has denies that any of its representatives are calling people telling them their computer may be at risk.

In a statement this morning, Microsoft Malta said it was aware of a seemingly ongoing scam whereby local individuals have been receiving calls from people identifying themselves as Microsoft representatives.

"These unknown callers inform the individual that their computer might be at risk and that they are in a position to run some diagnostics tests only after they purchase software to protect their machines in which case, the unknown callers are asking individuals for their personal credit card details.

"Microsoft Malta denies any involvement in such activity and confirms that this is an outright and harmful scam.

"Microsoft Malta advises the general public not to take heed of such phone calls.

"The company never runs any form of diagnostics tests over the phone and never seeks to sell any of its products to individual customers over the phone.

"An effective way how to ensure that customers run no such risks is by ensuring they use genuine software which may be downloaded for free from the Microsoft Security Essentials section on Microsoft's official website."

Microsoft said it was constantly active in investigating and taking action against any form of fraud when found, including taking legal action where necessary.

"As such, Microsoft Malta always urges the public to never give sensitive information such as personal details and credit card details over the phone and any individuals who experience a similar incident are urged to immediately report it to the respective authorities.

"In the case of any contact from third parties claiming to be representing Microsoft, the public is encouraged to contact the local Microsoft office to confirm the validity of any such situations," the company said.
