Happy 4th of July !!!
Remember to do your full backups at this time . If you cant do it on a regular basis (weekly or monthly) at least do some 2z a year. In July and December for example.
The only way is to have backups, update your systems, anti-virus software. and more.

In the book I am trying to teach “how to fish” so you can do this yourself.
