Yes ,wiped clean, erased. I thought and it may be so, that malware was involved. But it happened seconds after I turned on the computer and an update occurred. A search showed many people have experienced the same thing at some time. Dell Latitude on win 10.
This seems a little vague to me. Can you give us more details of what happened (i.e. computer activities before your computer was wiped clean, etc.)? Also, is there any instance that made you say it's because of malware?
