I love my Carbonite. Better check the settings. I have this peace of mind.
The computer gremlins are vicious. I've had to return mine to factory settings once in August and then right before Christmas after I finished the last design. Learned a lot from the August reset and after Christmas things went smoothly. Like you my information was backed up and I only lost a few designs. Our daughters computer got a trojan a couple weeks ago and it took me an hour to get it off after she tried for three hours and was about to restore to factory settings.. Wish I could have gotten that lucky on mine and we have the same virus protection. I do feel your frustration as if they don't have something better to do than mess up our computers.
Love ya and hope Dave can get everything up and running soon.
Yes, we have all been through something similar. Very frustrating. Here's a quick fix, but not a very bright one in the end. ;)
