Having a good computer guy is so important, just like a good car mechanic or baby sitter, etc. Often times, your whole life is on your computer and it is essential that you are able to trust your tech with all your personal information.
It would be easy for any tech worth their salt to gain access to all of your user names and passwords to your bank accounts, e-mail accounts, paypal, EBay, you name it – all the things that you really need to keep to yourself and it would be a disaster if they got into the wrong hands.
Choosing someone to fix your computer is a big decision, make sure that you can trust them. Sure, you can find someone on Gumtree who says he can work miracles for twenty bucks but would you trust them with all of the above information? I wouldn’t and nor should you.
