I had a call from "Windows Technical Support" this evening 'offering' to help fix my computer as it is apparently going slow due to all the junk files on my pc. The woman who rang was very insistent but I refused to turn on my computer and told her no chance was I doing anything based on an unsolicitated phonecall from a company I didn't know.
It is a scam - this is a link from MS on the topic, script was similar only I didn't turn on my pc and they claimed to be calling from Sydney: http://answers.microsoft.com/en-us/w...a-b6fb8db7c4d2
Most people will be aware its a scam, but thought I'd share just in case!
