Have tried multiple scans including deep and limited to a few files. All have netted zero positive results. The program takes up to 24 hours to complete a scan and will become unresponsive after co0mpleteing the scan. A contacted them a few days ago about the problem but only received advise on trying different scans. I have now downloaded a trial version of a different for program and completed a scan in less than 2 hours. I will seek refund from stellar.
