Good morning,

I use macOS Sierra 10.12.3 on an iMac 21 1/2", 2.7gHertz Intel Core i5 Processor - I found, yesterday, that all of my contacts within the above application, bar seven, had been cleared. While this is very annoying, I would like to know how to get them 'back'?

I do run a backup storage option through Time Machine and may have to be walked through this.

Now what could have caused this list of deletions? I have been subjected to the Zeus Trojan, and thought that this had been cleared ....

Has this happened to others?
