You can restore files if Portable Security fixed and quarantined files that you need.
Restoring these files may put your security at risk. You have to be very sure that the files are NOT infected before restoring the files because Trend Micro does not guarantee the safety of your devices if you restore infected files.
Restoring files can be only performed on a computer after Portable Security has quarantined a file and the files can only be restored on the same computer.
You have to be absolutely sure that the file is essential and that the file is not infected.
