The Ministry of Consumer Affairs advises people to be wary of a phone scam in which people are tricked into giving strangers access to their home computers.
The ministry says it has received numerous reports from people who have had cold calls from companies claiming to be able to clear their computer of a virus.
It says those who have been a victim of the scam report that the companies get remote access to the computer, and convince them there are costly problems that need to be fixed.
Consumer Affairs says while there are some legitimate companies who specialise in fixing computers, people should always be wary of giving their PC details over the phone.
