I conacted the ACCC who records scams in Australia.  This is a scam that has been registered with the Australian Government and they are trying to shut it down.  I didn't fall for it because I work for the NTG and had heard rumours about this scam running since August.  Steer clear!Also...Windows dont call you they email you.  Also beware of the current paypal scam...the website it directs you to update your credit card details is paypol not paypal.com.au.

this scam or fake calls are received when the personal computer has the viruses and this is time to get the expertise advice.

Just got of the phone to a group that sounded legit about computor malware.  Not sure if it is the same number but they all had Indian accents.  Almost got to believe until I got directed to www.microtechcare.com and was asked to paypal or credit card charge,  They gave the impression at first of being from microsoft support which did win some trust but am now worried that they have access to my computor

Complete Scam! now rife in the UK. Do not fall for it. Scammers are thieves hiding behind their keyboards. Glad to say authorities are on to it and close to putting the perpetrators behind bars where they belong. The Scammers are based in Calcutta, India and have nothing to do with Microsft, Apple or Unix.

This is definitely a scam. I fell for it too, and they have wiped out all my mcafee files and infected my laptop. I got advice to cancel my credit card and change all my passwords. Most importantly I was told not to use the Internet until I have my laptop professionally cleaned out as they have probably turned it into a "zombie" which is infecting other computers. Arrrggghh!!!
