Thank goodness for MCS! They stopped several viruses from taking over our computers on many different occasions. Plus we use them for backup. All of our computers automatically are scanned for viruses and taken care of immediately all without us having to worry. Our backup is also done automatically for us… eliminating the need for me to remember to plug in a separate hard drive! Two less things for us to worry about. If we have a problem with one of our PCs, MCS responds quickly either remotely or by coming to the office. Fast and Friendly… I highly recommend them!
