I looked at my database with phpMyAdmin and clicked on the xoops_modules table it showed the following error:
#1034 - Incorrect key file for table 'xoops_modules'; try to repair it
Also, when I look at the shart of all my tables, 'xoops_modules' as well as a number of others are listed as "in use" in the Collation column.
Here's a screenshot from phpMyAdmin:

Is that normal?
Does that mean I got hacked?
It's strange but it happened to three sites at once. It sounds like a mailcious bot of some kind.
