hi, yeah I got a call from someone claiming to be from Microsoft, unfortunately I kinda fell for the scam by letting them have access over my computer although I have recently reformatted the computer when i gave them access to my computer I'm not too sure if my external hard drive was connected when this occurred but after I found out it was a scam I immediately did a complete system restore with the reformatting disk I got along with my laptop. right now I'm still not sure if I'm completely safe. any advice would be greatly appreciated thank you
