Hi,
It is a well known Scam used by many.
Microsoft does not contact you, unless YOU have made prior arrangements with them to do so.
There is a section in the link I am supplying you about this at the end of it
Read this Microsoft Information:
"Avoid tech support phone scams"
http://www.microsoft.com/security/online-privacy/avoid-phone-scams.aspx
Do not trust unsolicited calls. Do not provide any personal information.
Here are some of the organizations that cybercriminals claim to be from:
- Windows Helpdesk
- Windows Service Center
- Microsoft Tech Support
- Microsoft Support
- Windows Technical Department Support Group
- Microsoft Research and Development Team (Microsoft R & D Team)
These so-called "Microsoft" Tech Companies either want to sell you worthless software, or gain Remote Access to your Computer to try and steal your Banking and Credit Card details and to also carry out an Indentity Theft on you.
We all have errors and warnings in our event viewer
If you have given them Remote Access and you do Internet Banking, contact your Bank, explain it to them and change Passwords.
If you use your Credit Card online, cancel it and get a new one issued to you.
And the only way that you willl know that you are free of them is to save your Data and do a clean install of your Operating System.
Cheers.
