I had 2 calls today from PC Masters who appear to be in Sydney. I am suspicious that somehow my earlier enquiry to NAB had something to do with this.

Also been getting calls from this company on a daily basis for the last week. Claimed to be a Windows technician and that there was something wrong with the computer. They knew my name and I'm ex-directory so don't know where they got my number from. Beware!

Had a call from this number today.  I am always suspicious of any unsolicited calls, as I have registered not to receive any.  Its the usual scam technique.  The caller has a strong accent from overseas; Indian subcontinent, but pretends to be called John, Jack, James or Stacey, or any other Anglo-Saxon sounding name.  Say they are ringing from Windows, or Window's approved provider to make them sound convincing.  Explain that there is an urgent fault with your computer/error messages etc and you need to log on or go to their website etc.  Never want to give you a number to call or put you through to a supervisor and usually hang up if you ask too many questions.

I spoke to BT about this, because they are often calling from abroad its difficult for BT to block the calls apparently.  The BT guy said whatever you do don't log onto any website or give them any of your details.  Its definitely a scam.  Not sure what BT or any of the Office of Fair Trading, Consumer Direct, the Police's computer crime units, or local councils' trading standards teams are doing to combat it.  If enough people report these calls often enough to as many of these organisations as possible, then the annoyance factor to these statutory organisations will kick in and they will have to take action to shut them down.

(02) 8005 7298 was the number they were calling from apparently.  Time BT allowed caller dialing number from international calls as well.

The guardian has done a story on this!

I received exactly the same call as FG just minutes ago. They are preying on peoples inexperience of computers by getting them to check event viewer.

Event Viewer constantly generates alerts in one form or another (usually application errors - these are what the fraudsters rely on). This does not necessarily mean that there is anything wrong with your computer at all.

As someone Studying for a degree in computer security I had a long winded conversation with the 'gentleman' on the other side of the line and proved that there was nothing wrong with my machine, at which point he hung up on me.

Calls from this number are a scam, they lure you to a website and get you to enter contact and payment details for them to remotely fix your pc.

There calls should be reported as fraud using the fraud reporting tool on the Mets fraud website www.actionfraud.org.uk - it takes a couple of minutes and you don't have to provide your own details unless you want to.

Had a from this number , lady with broken english claiming to be a windows technician and it had been reported that my PC had faults. Asked which company was she calling from but she just said windows computer company.  
I questioned on how did she know I had a fault. She demanded that i go straight to my pc and switch it on . I have more than one PC and requested if she new so much which one was it . Immediately  hung up on me !

Tried going through Online Fraud reporting - at the end I got this message (the online system didn't give me the option to report the phone number, so they are obviously not that interested):Thank you for taking time to complete the Action Fraud report. From the answers you have given we believe that this is a matter that should be reported to Consumer Direct. Consumer Direct are a Government funded service who take reports on scams.0845 404 0506 or Minicom 0845 1281 384. Open 8am - 8pm Monday to Friday and 9am to 1pm on Saturday.www.consumerdirect.gov.ukThere was no obvious section on their website to report the fraudulant number/organisation, so I gave up. Maybe someone with more time to spare might do this.
