Never ever allow remote access to someone who calls you about a possible problem with your computer. If you are tempted to allow remote access to your computer to someone whose credentials you can’t verify, just don’t do it.
If a smarter person is urging you away from allowing a stranger remote access to your computer, please listen. Listen even if that person is your silly spouse, the one overly cautious about nearly everything, and knows next to nothing about computers.
If remote access is granted to an unknown actor, there are actions you can take.
- Run an internal diagnostic
- Change passwords and update security protocols at sensitive sites, such as your banking institutions.
- When the inevitable problems occur, then take your computer to a reputable person for service.
So now you know why my computer is in the shop, and I am writing on my tablet.
No reputable company will call you and ask for access to your computer for any reason. Never ever!
