I purchased Pappocom Sudoku, perhaps a year or so ago, and have been using it regularly ever since.
Today when I attempted to continue working on a game that I had started last night, my antivirus software (AVG) popped up a warning that it had detected a trojan. In the process of repairing the problem it erased the Sudoku executable.
Is this a known problem? If I reinstall am I likely to have the same issue? What's going on here?
