I had an interesting conversation with a company call
All Day Tec Support which then like this:
Your name came up as computer owner of a computer which is believe to be infected
How old is the computer?
Have you notice a general slowing up of the computer?
The call was then pass to a member of the technical team
Which guide me to the event viewer by hold down the window and R keys at the same time, then typing in the run box: eventvwr
Right click error then open view all instances of the event.
Then type in the run box www.ammyy.com this is to open up a remote support page so they can fix these errors for free.
But what happen in the background is your pc, is infected with viruses which steal your passwords, bank and credit details
All computer in the event viewer got thousands of critical, error and warning messages that all part of the wear and tear of a pc, it all technical stuff, nothing to worry about.
If you never receive one of these phone call the best way to deal with them is to say you do not have a computer or you use a mac, and report the scam to the internet crime complaint center (IC3)
This is what Microsoft say about these computer scam
