Asian guy claiming to be from BT (my supplier - NOT), and they had detected lots of activity on my account that suggested I was infected.
Wanted me to open Event Viewer - Windows Key + R "EVENTVWR"
Then told me about all the terrible info it showed me and wanted me to install Teamviewer.
My PC chose this moment to install updates and restart (oops!).
Not the first time I've had this scam tried on me, but a record of 12 minutes 17 seconds....
Best bet with anyone claiming to be from BT and saying you have an infection is to hang up, do NOT follow any instructions.
