Hi bob3160,
This is exactly the way we have come to learn all these things.
You, Bob, are old enough to know how this works, as well as I (just nearing 60 and a half years now).
The restoration tool is very handy to have in case you have recently used the recycle bin and emptied it.
A lot can be restored that way. That is the only option that is left out for/to him or if (again if) he could restore his system to a previous point, he would have it all back. It is the same with back-ups, you start not forgetting about these things until you have met with disaster, and even then we are slack, that is typically human: the spirit is willing, but the flesh you know, bob
is weak...
By the way all the best to you, and hope that the two of you (you and Alice) are in good health,
God bless you,
your avast webforum friend,
Damian
