  1. great post and the information is very useful for me .thanks for sharing with us

  2. Hey Obasi,

    I haven’t had a computer virus in years, knock on wood. I do have some anti virus programs, security programs, malware programs, a few things that I run on an occasion to check to make sure everything is okay.

    I don’t use the cloud services but I do back up my files every single day to 2 different services and devices. I learned my lesson back in 2007 when Hurricane Ike came through and when we lost power I lost my computer. It blew out a few devices in my home and I didn’t have a current backup of everything. Never again my friend, never again.

    Thanks for this information.
